8. Suppose that a book publisher was interested in the number of fiction paperbacks adult customers purchase per month. The publisher conducted a survey. In the survey, adult consumers were asked the number of fiction paperbacks they had purchased the previous month. The results are shown as follows: # of Books 2 3 4 5 7 9 Frequency 18 24 24 22 15 10 5 1 a. Use the frequency row to construct a histogram for the publisher survey. Make the width of one. b. What kind of distribution do you see? Symmetrical, left skewed, or right skewed? Use the following information to answer the next two exercises: Suppose one hundred eleven people who shopped in a special t-shirt store were asked the number of t-shirts they own costing more than $19 each. 40/111 39/111 30/111 25/111 23/111 Relative frequency 20/111 17/111 10/111 - 5/111 2/111 1 2 3 4 5 6 7 Number of T-shirts costing more than $19 eachQ. The percentage of people who own at most three tshirt costing more than $19 each is approximately: a. 21 b. 59 c. 41 d. cannot be determined 10. If the data were collected by asking the rst 111 people who entered the store, then the type of sampling is a, cluster to. simple random c. stratied d. convenience 11. Forty randomly.r selected students were asked the number of pairs of sneakers they owned. Let X = the number of pairs of sneakers owned. The results are as follows: a. Find the sample mean {it} h. Find the sample standard deviation (5} c. Find the quartiles (rst, second. third) Frequency 12 12
