You wish to test the following claim (Ha) at a
significance level of a = 0.001. For the context of
this problem, Hd
= µ2 –
uj where the first data set
represents a pre-test and the second data set
represents a post-test.
Ha: Hd + 0
0 = Prd :°H
You believe the population of difference scores is
normally distributed, but you do not know the
standard deviation. You obtain pre-test and post-test
samples for n = 24 subjects. The average
difference (post - pre) is d
deviation of the differences of sa = 17.3.
