Assume that the populations are normally distributed.

Test whether u1>u2 at the a=0.05 level of significance for the given sample data

Construct a 95% confidence interval about u1-u2

Population 1 Population 2

n 22 21

x 48.5 44.9

s 4.2 10.7

Find the test statistic for this hypothesis test______________________(round 2 decimal places as needed)

Determine the p-value for this hypothesis test__________________ (round to three decimal places as needed)

State the conclusion for the hypothesis test

A. Reject H0. There is sufficient evidence at the a= 0.10 level of significance to conclude that u1>u2

B. Do not reject H0. There is sufficient evidence at the a= 0.10 level of significance to conclude that u1>u2

C. Reject H0. There is not sufficient evidence at the a=.10 level of significance to conclude that u1>u2

D. Do not reject H0. There is sufficient evidence at the a= 0.10 level of significance to conclude u1>u2

The 95% confidence interval about u1-u2 is the range from a lower bound of_____ to an upper bound of__________(round to three decimal places as needed)
