1. Nine students in a science class separately weighed a small object on the same scale. The weights (in grams) recorded by each student are shown below. 6.2 6.0 6.0 15.3 6.1 6.3 6.2 6.329 6.2 The students want to determine as accurately as they can the actual weight of this object. Of the following methods, which would you recommend they use? a. Use the most common number, which is 6.2 b. Use the 6.329 since it includes more decimal places. c. Add up the 9 numbers and divide by 9. d. Throw out the 15.3, add up the other 8 numbers and divide by 8. 2. The following message is printed on a bottle of prescription medication: WARNING: For application to skin areas there is a 15% chance of developing a rash. If a rash develops, consult your physician. Which of the following is the best interpretation of this warning? a. Don’t use the medication on your skin-- there’s a good chance of developing a rash. b. For application to the skin, apply only 15% of the recommended dose. c. If a rash develops, it will probably involve only 15% of the skin. d. About 15 of 100 people who use this medication develop a rash. e. There is hardly a chance of getting a rash using this medication. 3. The Springfield Meteorological Center wanted to determine the accuracy of their weather forecasts. They searched their records for those days when forecasts had reported a 70% chance of rain. They compared their forecasts to records of whether or not it actually rained on those particular days. The forecast of 70% chance of rain can be considered very accurate if it rained on: a. 95%-100% of those days. b. 85%-94% of those days. c. 75%-84% of those days. d. 65%-74% of those days. e. 55%-64% of those days. 4. A teacher wants to change the seating arrangement in her class in the hopes that it will increase the number of comments her students make. She first decides to see how many comments students make with the current seating arrangement. A record of the number of comments made by her 8 students during one class period is shown below. ____ _Student Initials _ A.A R.F. A.G. J.G. C.K. N.K. J.L. A.W. Number of Comments 0 5 2 22 3 2 1 2 . She wants to summarize this data by computing the typical number of comments made that day. Of the following methods, which would you recommend she use? a. Use the most common number, which is 2. b. Add up the 8 numbers and divide by 8. c. Throw out the 22, and then add up the other 7 and divide by 7. d. Throw out the 0, add up the other 7 numbers and divide by 7. For items 5-6 A new medication is being tested to determine its effectiveness in the treatment of eczema, an inflammatory condition of the skin. Thirty patients with eczema were selected to participate in the study. The patients were randomly divided into two groups. Twenty patients in an experimental group received the medication, while ten patients in a control group received no medication. The results after two months are shown below. Experimental group (medication) Control group (no medication) Improved 8 Improved 2 No improvement 12 No Improvement 8 5. Based on the data, I think the medication was: a. somewhat effective b. basically ineffective 6. If you chose option a, select the one If you chose option b, select the explanation below that best describes one explanation below that best your reasoning. describes your reasoning. a. 40% of the people (8/20) in the a. In the control group, experimental group improved. two people improved even without medication. b. 8 people improved in the experimental b. In the experimental group, group while only 2 improved in the more people didn’t get control group better than did (12 vs. 8). c. In the experimental group, the number c. The difference between of people who improved is only 4 less the numbers who than the number who didn’t improve improved and didn’t (12-8), while in the control group the improve is about the difference is 6 (8-2). same in each group (4 vs. 6). d. 40% of the patients in the d. Only 40% of the patients in experimental group improved (8/20), the experimental group while only 20% improved in the improved (8/20), while 20%. control group (2/10). improved in the control group (2/10). Items 7-9 Listed below are several possible reasons one might question the results of the experiment described above. Mark A for every reason you agree with. A = Agree B = Disagree 7. It’s not possible to compare the two groups because there are different numbers of patients in each group. 8. With a sample size of 30, it’s possible that random assignment of patients may have, just by chance, placed the most severe cases in one of the groups. 9. I’m not given enough information about how doctors decided whether or not patients improved. Doctors may have been biased in their judgment. 10. Two containers, labeled A and B, are filled with red and blue marbles in the following quantities. Container Red Blue A 6 4 B 60 40 Each container is shaken vigorously. After choosing one of the containers, you will reach in, without looking, draw out a marble. If the marble is blue, you win $50. Which container gives you the best chance of drawing a blue marble? a. Container A (with 6 red and 4 blue) b. Container B (with 60 red and 40 Blue) c. Equal chances from each container. 11. Which of the following sequences is most likely to result from flipping a fair coin five times? (H=Heads, T=Tails) a. H H H T T b. T H H T H c. T H T T T d. H T H T H e. All four are equally likely Items 12-15 Select one or more explanations for possible coin-flipping outcomes. A = Agree B = Disagree 12. Since coin flipping is random, the coin ought to alternate frequently between landing heads and tails. 13. If you repeatedly flipped a coin five times, each of the sequences would occur about as often as any sequence. 14. If you get a couple of heads in a row, the probability of tails on the next flip increases. 15. Every sequence of five flips has exactly the same probability of occurring. 17. Listed below are the same sequences of H’s and T’s that were listed in Item 11. Which of the sequences is least likely to result from flipping a coin 5 times? a. H H H T T b. T H H T H c. T H T T T d. H T H T H e. All four sequences are equally unlikely Items 17-22 A marketing research company was asked to determine how much money teenagers (ages 13-19) spend on recorded music (cassette tapes, CD’s, and DVD’s). The company randomly selected 80 malls located around the country. A field researcher stood in a central location in the mall and passers-by who appeared to be the approximate age were asked to fill out the questionnaire. A total of 2,050 questionnaires were completed by teenagers. On the basis of this survey, the research company reported that the average teenager in this country spends $155 each year on recorded music. Listed below are several statements concerning the survey. Mark A for each statement you agree with. Mark B for each statement you disagree with. A = Agree B = Disagree 17. The average is based on teenagers’ estimates of what they spend and therefore could be quite different from what teenagers actually spend. 18. They should have done the survey at more than 80 malls if they wanted an average based on teenagers throughout the country. 19. The sample of 2,050 teenagers is too small to permit drawing a conclusion about the entire country. 20. They should have asked teenagers coming out of music stores. 21. The average could be a poor estimate of the spending of all teenagers given that teenagers were not randomly chosen to fill out the questionnaire. 22. The average could be a poor estimate of the spending of all teenagers given that only teenagers in malls were sampled. 23. Five faces of a fair die are painted black, and one face is painted white. The die is rolled six times. Which of the following results is more likely? a. Black side up on five of the rolls; white side up on the other roll b. Black side up on all six rolls c. a and b are equally likely 24. Half of all newborn children are girls and half are boys. Hospital A records an average of 50 births a day. Hospital B records an average of 10 births a day. On a particular day, which hospital is more likely to record 80% or more female births. a. Hospital A (with 50 births a day) b. Hospital B (with 10 births a day) c. The two hospitals are equally likely to record such an event. 25. The Caldwells want to buy a new car, and they have narrowed their choices to a Buick or an Oldsmobile. They first consulted an issue of Consumer Reports, which compared rates of repairs for various cars. Records or repairs done on 400 cars of each type showed somewhat fewer mechanical problems with the Buick than the Oldsmobile. The Caldwells then talked to three friends, two Oldsmobile owners, and one former Buick Owner. Both Oldsmobile owners reported having a few mechanical problems, but nothing major. The Buick owner, however, exploded when asked how he liked his car: “First the fuel injection went out-- $250 bucks. Next I started having trouble with the rear end and had to replace it. I finally decided to sell it after the transmission went. I’d never buy another Buick.” The Caldwells want to buy the car that is less likely to require major repair work. Given what they currently know, which car would you recommend that they buy? a. I would recommend they buy the Oldsmobile, primarily because of all the trouble their friend had with his Buick. Since they haven’t heard similar horror stories about an Oldsmobile, they should go with it. b. I would recommend they buy the Buick in spite of their friend’s bad experience. This is just one case, while the information reported in Consumer Report is based on many cases. And according to the data, the Buick is somewhat less likely to require repairs. c. I would tell them that it didn’t matter which car they bought. Even though one of the models might be more likely than the other to require repairs, they could still, just by chance, get stuck with a particular car that would need a lot of repairs. They may as well toss a coin to decide. 26. Forty college students participated in a study of the effect of sleep on test scores. Twenty of the students volunteered to stay up all night studying the night before the test (no sleep group). The other 20 students (the control group) went to bed by 11:00 p.m. on the evening of the test. The test scores for each group are shown in the graphs below. Each dot on the graph represents a particular student’s score. For example, the two dots above 80 in the bottom graph indicate that two students in the sleep group scored 80 on the test. . . . . . . . . . . . . . . . . . . . . 30 40 50 60 70 80 90 100 Test Scores: No- Sleep Group . . . . . . . . . . . . . . . . . . . . 30 40 50 60 70 80 90 100 Test Scores: Sleep Group Examine the two graphs carefully. Then choose from the 6 possible conclusions listed below the one you most agree with. a. The no-sleep group did better because none of these students scored below 40 and, a student in this group achieved the highest score. b. The no-sleep group did better because its average appears to be a little higher than the average of the sleep group. c. There is no difference between the two groups because there is considerable overlap in the scores of the two groups. d. There is no difference between the two groups because the difference between their averages is small compared to the amount of variation in the scores. e. The sleep group did better because its average appears to be a little higher than the average of the no sleep group. Items 27-31 For one month, 500 elementary students kept a daily record of the hours spent watching television. The average number of hours per week spent watching television was 28. The researchers conducting the study also obtained report cards for each of the students. They found that the students who did well in school spent less time watching television than those students who did poorly. Listed below are several possible statements concerning the results of this research. Mark A for each statement you agree with. A = Agree B = Disagree 27. The sample of 500 is too small to permit drawing conclusions. 28. If a student decreases the amount of time spent watching television, his or her performance in school would improve. 29. Even though students who did well watched less television, this doesn’t necessarily mean that watching television hurts school performance. 30. One month is not a long enough period of time to estimate how many hours the students really spend watching television. 31. The research demonstrates that watching television causes poorer performance in school. Items 32-37 The school committee of a small town wanted to determine the average number of children per household in their town. They divided the total number of children in the town by 50, the total number of households. Indicate which statements must be true if the average number of children per household is exactly 2.2. Mark A for the statements you agree with and B for the statements you disagree with. A = Agree B = Disagree 32. Half of the households in the town have more than 2 children. 33. More households in the town have 3 children than have 2 children. 34. There are 110 children in the town. 35. There are 2.2 children in the town for every adult. 36. The most common number of children in a household is 2. 37. More households in the town have 2 children than have 3 children. 38. When two dice are simultaneously thrown it is possible that one of the following two results occurs: Result 1: A 5 and a 6 are obtained. Result 2: A 5 is obtained twice. Select the response that you agree with most: a. The chance of obtaining each of these results is equal. b. There is more chance of obtaining Result 1. c. There is more chance of obtaining Result 2. d. It is impossible to give an answer. 39. When three dice are simultaneously thrown, which of the following results is MOST LIKELY to be obtained? a. Result 1: A 5, a 3 and a 6 b. Result 2: A 5 three times c. Result 3: A 5 twice and a 3 d. All three results are equally likely 40. When three dice are simultaneously thrown, which of these three results is LEAST LIKELY to be obtained? a. Result 1: A 5, a 3 and a 6 b. Result 2: A 5 three times c. Result 3: A 5 twice and a 3 d. All three results are equally unlikely

At a shop of marbles, packs of marbles are prepared. Packets are named A, B, C, D, E …….. All packets are kept in a VERTICAL SHELF in random order. Any numbers of packets with these names could be kept in that shelf as in this example: bottom of shelf ---> [AAAJKRDFDEWAAYFYYKK]-----Top of shelf. All these packets are to be loaded on cars. The cars are lined in order, so that the packet could be loaded on them. The cars are also named [A, B, C, D, E,………….]. Each Car will load the packet with the same alphabet. So, for example, car ‘A’ will load all the packets with name ‘A’. Each particular car will come at the loading point only once. The cars will come at the loading point in alphabetical order. So, car ‘B’ will come and take all the packets with name ‘B’ from the shelf, then car ‘C’ will come. No matter how deep in the shelf any packet ‘B’ is, all of the ‘B’ packets will be displaced before the ‘C’ car arrives. For that purpose, some additional shelves are provided. The packets which are after the packet B, are kept in those shelves. Any one of these shelves contains only packets, having the same name. For example, if any particular shelf is used and if a packet with name X is in it, then only the packets having names X will be kept in it. That shelf will look like [XXXXXXX]. If any shelf is used once, then it could be used again only if it is vacant. Packets from the initial shelf could be unloaded from top only. Write a program that finds the minimum total number of shelves, including the initial one required for this loading process.
