Question
Assume that both populations are normally distributed. a) Test whether H, >H, at the a = 0.10 level of significance for the given sample data. Sample 1 Sample 2 19 12 b) Construct a 90% confidence interval about u, - H2. 45.3 37.7 9 8.2 E Click the icon to view the Student t-distribution table. a) Perform a hypothesis test. Determine the null and alternative hypotheses. O A. Ho: H1 > H2, HqHq <H2 O B. Ho: H1 <H2, Hq:Hq>H2 OC. Ho: H1 = H2, H4: H1 <H2 D. Ho: H1 = H2, Hq: Hy> H2 Determine the test statistic. (Round to two decimal places as needed.)
