Desperate for Help..Statistics :-( Please help if u can?

Question

1.Assume the following: Ho: P1 - P2 = 0; Ha: P1- P2 > 0; large random samples, alpha = .05. What critical value(s) would lead you to reject the null hypothesis in favor of the alternative hypothesis?
2. Assume the following: Ho: U1 - U2 = 0; Ha: U1- U2 ne 0; small random samples (n1 = 15, n2 = 13); alpha = .05. What critical value(s) would lead you to reject the null hypothesis in favor of the alternative hypothesis?

4. Assume the following: Ho: P1 - P2 = 0; Ha: P1- P2 ne 0; large random samples, alpha = .05. What critical value(s) would lead you to reject the null hypothesis in favor of the alternative hypothesis?
5. The critical value of test statistic based on the alpha level and nature of the alternative hypothesis is Z = - 1.96. Your obtained z-score based on your sample statistics is Z = + 2.88. What decision do you make in this case about the null hypothesis?

Answer 1

1. This is a one-sided test, using a Z score. Check the table in your text book.



2. This is a two-sided test, using the t-test. Check the t distribution table.



3. One-sided t-test.



4. Two-sided z scores.



5. I don't think this question is well-stated, but assuming that the null hypothesis is that two groups are the same, then you would not reject the null hypothesis.
