I also need to construct a 95% confidence interval about m1-m2 (question was cut off).

Assume that both populations are normally distributed Population 1 Population 2 (a) Test whether my # 12 at the a= 0 05 level of significance for the given sample data 19 19 (b) Construct a 95% confidence interval about 14 - 12 10 4 12 22 28 (a) Test whether p, # 12 at the a= 0 05 level of significance for the given sample data Determine the null and alternative hypothesis for this test O A HOP1 = 2 OB. HOW1 = 12 H1 71 > H2 OC. Holy* 12 H1 71 > H2 OD. HOPI # 12 H1 141 = 12 Determine the P-value for this hypothesis test. P=(Round to three decimal places as needed.) Should the null hypothesis be rejected? O A. Do not reject Ho. there is not sufficient evidence to conclude that the two populations have different means O B. Reject Ho, there is sufficient evidence to conclude that the two populations have different means
