Question

The following table gives the frequency distribution of times (to the nearest hour) that 90 fans spent waiting in line to buy tickets to a rock concert. Circle the correct answer in each of the following statements, which are based on this table. a. The number of classes in the table is 5, 30, 90. b. The class width 6, 7, 34. c. The midpoint of the third class is 16.5, 17, 17.5. d. The lower boundary of the second class is 6.5, 7, 7.5. e. The upper limit of the second class is 12.5, 13, 13.5 f. The sample size is 5, 90, 11. g. The relative frequency of the second class is .22, .41, .30.

Explanation / Answer

A) Number of classes = 5

B) class width = 6-0 = 6

C) midpoint of 3rd class = (14+20)/2 = 17

D) Lower boundary of second class = 7-0.5 = 6.5

E) Upper limit of second class = 13

F) sample size = (5+27+30+20+8) = 90

G) Relative frequency of second class = 27/90 = 0.3
