Question

B. The test​ statistic, t=____

C.The​ P-value is_____

D.State the conclusion for the test.

Reject the null hypothesis or Fail to reject the null hypothesis.
 
E. Construct a confidence interval appropriate for the hypothesis test in part​ (a).
___lb<μ1−μ2<____lb
 
F. Does the confidence interval support the conclusion found with the hypothesis​ test?
(No/Yes) because the confidence interval contains  (only negative values/ only positive values/ zero.)
