Identify the null hypothesis, alternative hypothesis,
test statistic, P-value, conclusion about the null hypothesis, and
final conclusion that addresses the original claim. Use the P-value
method.
A study was done on body temperatures of men and women. Here are
the sample statistics for the men: x1 = 97.55oF, s1 = 0.83oF, n1 =
11, and for the women: x2 = 97.31oF, s2 = 0.65oF, n2 = 59. Use a
0.06 significance level to test the claim that µ1 > µ2.

4) Test the hypothesis that μ1 ≠ μ2. Two samples are randomly
selected from each population. The sample statistics are given
below. Use α = 0.02.
n1 = 51
x1=1
s1 = 0.76
n2 = 38
x2= 1.4
s2 = 0.51
STEP 1: Hypothesis: Ho:________________ vs H1:

are normally distributed, but you do not know the standard
deviations for either. And you have no reason to believe the
variances of the two populations are equal You obtain a sample of
