Let's say we believe that desk-officers and patrol-officers spend different get differing numbers of overtime hours because of their different assignments. We take a small sample of each group to determine if they are truly different. Conduct a two mean hypothesis test to ascertain whether there is a difference between desk-officers and patrol-officers regarding overtime. Use a significance level of = 0.01 and the information below.

Desk Officers	Patrol Officers
n = 4	n = 7
s1 = 2.9	s2 = 2.0
