Population 1 Population 2 Assume that both populations are normally distributed. 19 19 (a) Test whether , # H2 at the a = 0.01 level of significance for the given sample data. n X 17.9 12.5 (b) Construct a 99% confidence interval about H1 - H2. S 3.9 4.6 (a) Test whether , # H2 at the a = 0.01 level of significance for the given sample data. Determine the null and alternative hypothesis for this test. A. HO:H1 = H2 H1:My * H2 O B. HO:H1 # H2 H1:H1 = H2 O C. HO:H1 # H2 H1: H1 > H 2 OD. HO:H1 = H2 H1: H1 > H2 Detemine the P-value for this hypothesis test. P= (Round to three decimal places as needed.)
