7) Answer the questions below for hypothesis A and B.

1.What is the test statistic? ​(Round to two decimal places as​ needed.)

2. What are the critical values? ​(Round to three decimal places as​ needed.)

3. Since the test statistic (falls/does not fall) in the rejection region, (reject/do not reject) Ho. There is (sufficient/ not sufficient) evidence to conclude that the mean of population 1 is different from population 2.

4.What is the P value?

5. Since the p-value is (greater then/less then) a, (reject, do not reject) Ho. There is (sufficient/ not sufficient) evidence to conclude that the mean of population 1 is different from population 2.

------------------------------------------------------------------------

Hypothesis 1

Ho; μ1−μ2=0

H1; μ1−μ2≠0

x1=224; x2=119

​sigma1=65; sigma2=57

n1=47 n2=35

------------------------------------------------------------------------

Hypothesis 2

H0: μ1−μ2≥0

H1: μ1−μ2<0

x1=127; x2141

sigma1=36; sigma2=39

n1=55;n2=40
