Consider the following hypothesis statement using and data from two independent samples. Assume the population variances are equal and the populations are normally distributed. Complete parts a and b. H0: μ1−μ2≤8

x1=72.2
x2=56.4
H1: μ1−μ2>8
s1=17.5
s2=15.9
n1=20
n2=22

Required:
Calculate the appropriate test statistic and interpret the result.

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.
