In order that patients don’t experience excessive wait times, Aston Medical Center’s goal is for the standard deviation for the time doctors spend with their patients to be less than 6.0 minutes. To determine if this goal is being met, a random sample of times the center’s doctors spent with their patients was collected. These data can be found in the Excel file Aston.xlsx. The times are as follows:

a. Using α = 0.10, determine if the goal set by Aston Medical Center is being met.

b. Verify your results using PH_Stat.

c. Interpret the p value obtained from the software.
