It has been stated that the average life span of a man is 75 years. A study was conducted of a sample of men in a small town who had died in the last 2 months. Their ages at death were 60, 72, 73, 79, 80, 82, and 89.
Using alpha of 0.05 determine if there is evidence for a treatment effect.

H0: mu = 75
Ha: mu > 75
test statistics:
t = (x -mean)/(s/sqrt(n))
= ( 76.4286 - 75)/(9.2170/sqrt(7))
= 0.4101
