Name: ____________________________________________ 1. (True or False) For a two-sided test, if the test statistic t 0 is less than α then we can reject the null hypothesis. (Compare to critical values, not α) 2. Suppose we conduct a one-sided hypothesis test on a mean, and the critical value is found to be -1.64 with α = 0.05. For which of the following null hypotheses is the conclusion correct (choose all that are correct)? a. H0: μ = 50; Fail to reject H0 b. H0: μ = 50; Reject H0 c. H0: μ = 0; Fail to reject H0 d. H0: μ = 0; Reject H0 e. We cannot draw any of these conclusions from the data provided. (You would need the test statistic or the sample mean, standard deviation, and number of observations) 3. Which of the below is the proper definition of power? a. P(Reject H0|H0 is true) b. P(Reject H0|H0 is false) c. P(Fail to reject H0|H0 is true) d. P(Fail to reject H0|H0 is false) e. None of the above (You want the test to have high power. High power means you can reject the null hypothesis whenever it is false.) 4. (True or False) When given the critical values t α/2 and –t α/2 , we can obtain the p-
