Use the given statistics to complete parts (a) and (b). Assume that the populations are normally distributed. (a) Test whether H1 > H2 at the a = 0.05 level of significance for the given sample data. (b) Construct a 90% confidence interval about 1 - H2. (a) Identify the null and alternative hypotheses for this test. OB. HO: H1 > H2 O A. HO: H1 = H2 H1: 41 = H2 Hy: Hy

H2 Find the test statistic for this hypothesis test . (Round to two decimal places as needed.) Tutoring Textbook Get more help - MacBook Air
