Alexandra Linder MATH 1710 Th 1:25 PM Exercises 1. 50 simulations in which a coin is thrown 100 times. This histogram describing the number of times a head is thrown is unimodal-there is only one peak. It is not symmetrical. 2. a. One Bernoulli trial is a one question. The probability of success is ¼ or .25. There will be 7 trials in the experiment. b. This histogram shows the number of questions you will guess correctly in 100 cases. c. This histogram is unimodal. It is different from the histogram shown above because the possible distribution is much smaller-here there range is much smaller than above. Also there is one

Unformatted text preview: result here, 2, that is most prevalent with 36 occurrences. The most common one above has only 13 occurrences. You have a 26/50, or slightly more than 50%, chance of getting a 3 or 4 on this test. d. 50 multiple choice questions. Even though there are 50 questions now instead of 7, it is virtually impossible to get a good grade on this test-the highest possible grade in this distribution is 21/50. As the number of questions increases, you are less likely to get a passing grade on the test....
