Question

(a) Test whether μ1 ≠ μ2 at the α=0.05 level of significance for the given sample data

(b) Construct a 95 % confidence interval about μ1-μ2.

(a) Test whether μ1 ≠ P2 at the α=0.05 level of significance for the given sample data. Determine the null and alternative hypothesis for this test.

Determine the P-value for this hypothesis test.

P=_______ (Round to threes decimal places as needed.)

Should the null hypothesis be rejected?

A. Reject H0, there is not sufficient evidence to conclude that the two populations have different means.

B. Do not reject H0. there is not sufficient evidence to conclude that the two populations have different means.

C. Reject H0, there is sufficient evidence to conclude that the two populations have different means.

D. Do not reject H0, there is sufficient evidence to conclude that the two populations have different means.

(b) Construct a 95 % confidence interval about μ1-μ2
