25 The data to the right represent the number of customers waiting for a table at 6:00 P.M. for 40 consecutive Saturdays at Bobak's Restaurant. Complete parts (a) through (h) below. (a) Are these data discrete or continuous? Explain. (b) Construct a frequency distribution of the data. Number of Customers 1-3 4-6 7-9 (c) Construct a relative frequency distribution of the data. Number of Relative Frequency Customers 1-3 10-12 13-15 Frequency A. OA. The data are continuous because it was recorded for 40 consecutive Saturdays. B. The data are discrete because it was recorded for 40 consecutive Saturdays. OC. The data are discrete because there are a finite or countable number of values. O D. The data are continuous because there are a finite or countable number of values. 4-6 7-9 1852963 A.

The distribution is skewed right because the right tail is longer than the left tail. OB. The distribution is skewed left because the right tail is longer than the left tail. O C. The distribution is symmetric because the bars in the histograms are all approximately the same height. O D. The distribution is skewed left because the left tail is longer than the right tail. O E. The distribution is symmetric because the left and right sides are approximately mirror images. O F. The distribution is skewed right because the left tail is longer than the right tail.
