The mean waiting time for customers in a single line is_minutes.
The median waiting time for customers in a single line is_minutes.
The mean waiting time for customers in individual lines is _minutes.
The median waiting time for customers in individual lines is_minutes.
Determine whether there is a difference between the two data sets that is not apparent from a comparison of the measures of center. If so, what is it?
A.
The times for customers in a single line are much more varied than the times for customers in individual lines.
B.
The times for customers in individual lines are much more varied than the times for customers in a single line.
C.
There is no difference between the two data sets.
The mean waiting time for customers in a single line is 7.17
The median waiting time for customers in a single line is 7.15
The mean waiting time for customers in individual lines is 7.17 minutes.
The median waiting time for customers in individual lines is 7.15 minutes.
option B is correct:
The times for customers in individual lines are much more varied than the times for customers in a single line.

The data table contains waiting times of customers at a bank, where customers enter a single waiting line that feeds three teller windows. Test the claim that the standard deviation of waiting times is less than 2.2 minutes, which is the standard deviation of waiting times at the same bank when separate waiting lines are used at each teller window. Use a significance level of .05. Complete parts (a) through (d) below Compute the test statistic. Find the p value
