Two-tailed Test using Statdisk to Compute T-tests (Statistics Project Sample)

Instructions:

A local hospital states their average emergency room wait time to see a physician is less than 30 minutes. 
The standard deviation is not known. 
A survey of ten (10) randomly selected patient records is that the null hypothesis is that the mean wait time also is presumed to be 30 minutes. The data for each record surveyed 27, 31, 26, 30, 29, 30, 31, 28 30, 30 minutes.
