(a) Draw a relative frequency histogram with lower class limit of the first class equal to 0 and class width 20. A. Frequency O C. Frequency Wait Time (in minutes) at Dinosaur Ride 30- 25- 20- 15- 10- 5- 30- 25- 20- 20 15- 10- 5- Wait Time (in minutes) at Dinosaur Ride 40 Wait Time 20 40 Wait Time 60 A. The distribution is skewed right. B. The distribution is uniform. C. The distribution is skewed left. O D. The distribution is bell-shaped. 60 80 80 (b) Comment on the shape of the distribution. Choose the correct answer below. OA. Yes. The correlation between the expected z-scores and the observed data, population. B. No. The correlation between the expected z-scores and the observed data, normal population. OC. Yes. The correlation between the expected z-scores and the observed data, population. D. No. The correlation between the expected z-scores and the observed data, normal population. exceeds the critical value, does not exceed the critical value, exceeds the critical value, Frequency O Frequency does not exceed the critical value, B. Wait Time (in minutes) at Dinosaur Ride 30- 25- 20- 15- 10- 5- D. 0 (c) Is it reasonable to conclude that the variable "Wait Time" is approximately normally distributed? Note: Use the critical value for n = 30 from the table provided. Select the correct choice below and fill in the answer boxes to complete your choice. (Round to three decimal places as needed.) 30- 25- 20- 20 15- 10- 5- Wait Time (in minutes) at Dinosaur Ride 40 Wait Time 20 40 Wait Time 60 60 80 Therefore, it is reasonable to conclude that the data come from a normal 80 Therefore, it is not reasonable to conclude that the data come from a Therefore, it is not reasonable to conclude that the data come from a normal Therefore, it is reasonable to conclude that the data come from a
