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 a = 0.05 level of significance for the given sample data. n 21 22 51.2 40.2 4.8 12.3 (a) Identify the null and alternative hypotheses for this test. OA. HO: M1 = H2 OB. HO: My H2 Hy: My = H2 H1: My = H2 OD. HO: H1 > H2 OE. HO: M1 = H2 OF. HO: M1 = H2 H1: My = H2 Hy: My # H2 Hy: My H2. O B. Reject Ho. There is sufficient evidence at the a = 0.05 level of significance to conclude that , > M2. O C. Reject Ho. There is not sufficient evidence at the a = 0.05 level of significance to conclude that H, > H2. Clear all Check
