A data set represents the wait time (in minutes) for a random sample of 100 visitors to Disney's Dinosaur Ride in Animal Kingdom. Technology was used to obtain a random sample of 40 observations from the original sample of 100 visitors. Complete below.

Select the correct choice below and fill in the answer boxes to complete your choice. (Round to three decimal places as needed.) O A. No. The correlation between the expected z-scores and the observed data,. does not exceed the critical value, Therefore, it is not reasonable to conclude that the data come from a normal population.

(b) Comment on the shape of the distribution, Choose the correct answer below.
O A. The distribution is skewed left.
O B. The distribution is uniform
O C. The distribution is bell-shaped.
D
The distribution is skewed right.
(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.)
O A. No. The correlation between the expected z-scores and the observed data,
does not exceed the critical value,
Therefore, it is not reasonable to conclude that the data come from a normal population.
O B. Yes. The correlation between the expected z-scores and the observed data,
exceeds the critical value,
Therefore, it is reasonable to conclude that the data come from a normal population.
O C. Yes. The correlation between the expected z-scores and the observed data,
exceeds the critical value,
Therefore, it is not reasonable to conclude that the data come from a normal population.
O D. No. The correlation between the expected z-scores and the observed data,
does not exceed the critical value,
Therefore, it is reasonable to conclude that the data come from a normal population.
