Question
You wish to test the following claim (H.) at a significance level of a= 0.002. For the context of this
problem, = P2-A where the first data set represents a pre-test and the second data set represents a
post-test.
H. = 0
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 = 10 subjects. The average difference (post - pre)
is d
-32.1 with a standard deviation of the differences of sa = 36.7.
