Ms. Lisa Monnin is the budget director for the New Process Company. She would like to compare
the daily travel expenses for the sales staff and the audit staff. She collected the following sample
Sales: 131, 135, 146, 165, 136, 142
Audit: 130, 102, 129, 143, 149, 120, 139
At the .10 significance level, can she conclude that the mean daily expenses are greater
for the sales staff than the audit staff? What is the p-value? (Show all work)
This solution shows details of an independent samples t-test for the difference between two population means.
