The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject He when the level of significance is (a) a = 0.01, (b) a = 0.05, and (C) a = 0.10. P = 0.0695 (a) Do you reject or fail to reject He at the 0.01 level of significance? O A. Fail to reject H, because the P-value, 0.0695, is greater than a = 0.01. O B. Fail to reject H, because the P-value, 0.0695,...

1) Identify the rejection point(s) for the test of the following hypothesis: H0: mean = 10, Ha: mean != 10 Conducted on a sample size of 15, on a normally distributed population with unknown population variance, and a desired Type1 error probability (alpha) of 0.05. Hint: use the appropriate statistical function in your spreadsheet to determine the rejection point. Z test with rejection points -1.64 and +1.64 Z test with rejection points -1.96 and +1.96 t-test with degrees of freedom=14,...

For the following information, determine whether a normal sampling distribution can be used, where p is the population proportion, a is the level of significance, p is the sample proportion, and n is the sample size. If it can be used, test the claim. Claim: p20.47; a = 0.06. Sample statistics : P = 0.40, n = 150 Let q=1-p and let = 1-P. A normal sampling distribution be used here, since v and If a normal sampling distribution can...
