Question 46 (page 181) DI, Richmond, a psychologist, is studying the daytime television viewing habits of college students. She believes 45% of college students watch soap operas during the afternoon. To further investigate, she selects a sample of 10. a) Develop a probability distribution for the number of students in the sample who watch soap operas. b) Find the mean and the standard deviation of this distribution. c) What is the probability of finding exactly four students who watch soap operas? d) What is the probability less than half of the students selected watch soap operas? Question 56 (page 182) According to sales information in the first quarter of 2016, 2.7% of new vehicles sold in the United States were hybrids. This is down from 3.3% for the same period a year earlier.

8.The data show the daily high temperature in a town every day for a week. Mon Tue Wed Thu Fri Sat Sun 76∘F 78∘F 81∘F 74∘F 69∘F 69∘F 70∘F How can you find the experimental probability that the high temperature on a given day was warmer than 75∘F? Count the number of days with temperatures above 75∘F and divide that number by the number of days in the week. Count the number of days with temperatures below 75∘F and divide that number by .75∘F. Count the number of days with temperatures above 75∘F75∘F and divide that number by 75∘F. Count the number of days with temperatures above 75∘F and divide that number by the number of days with temperatures below 75∘F.
