question 1: Assume that both...? question 2: assume that both...?

Assume that both populations are normally distributed. Population 1 Population 2 (a) Test whether u, # u2 at the a = 0.01 level of significance for the given sample data. 16 16 (b) Construct a 99% confidence interval about , - H2 11.9 9.4 3 3.2 Determine the P-value for this hypothesis test. P= (Round to three decimal places as needed.) Should the null hypothesis be rejected? O A. Reject Ho. there is not sufficient evidence to conclude that the two populations have different means. 18. Reject Ho, there is sufficient evidence to conclude that the two populations have different means. O C. Do not reject Ho, there is sufficient evidence to conclude that the two populations have different means. O D. Do not reject Ho, there is not sufficient evidence to conclude that the two populations have different means. (b) Construct a 99% confidence interval about w, - H2 We are 99% confident that the mean difference is between and (Round to two decimal places as needed. Use ascending order.)
