Use the given statistics to complete parts (a) and (b). Assume that the populations are normally distributed. Population 1 Population 2 (a) Test whether H, > H2 at the o = 0.01 level of significance for the given sample data. 20 17 CO X1 5 (b) Construct a 95% confidence interval about 1 - H2. 45.9 41.4 6.4 12.9 (a) Identify the null and alternative hypotheses for this test. OA. HO: My

H2 OD. HO: My = H2 OE. HO: My # H2 OF. HO: H1 > H2 Hy : Hy H2. B. Do not reject Ho. There is not sufficient evidence at the a = 0.01 level of significance to conclude that Hy > H2. C. Do not reject Ho. There is sufficient evidence at the a = 0.01 level of significance to conclude that My > #2- O D. Reject Ho. There is not sufficient evidence at the a = 0.01 level of significance to conclude that Hy > H2. (b) The 95% confidence interval about 1 - H2 is the range from a lower bound of to an upper bound of ]. (Round to three decimal places as needed.)
