Consider a two tailed hypothesis test. The null and alternative hypotheses are presented below Ho 100 H1 : μ 100 a. Suppose the test statistic1.44. Find the p-value of the test and the critical value for the test when α-001. Then show that the conclusion using the critical value approach will be identical to the conclusion based on the p-value b. Now suppose the test statistic is ะ-_301. Find the p-value of the test and the critical value for the...

Consider conducting a hypothesis test in which the null and alternative hypotheses are: Ho: ? ? c Ha: ? > c Where c is some hypothesized value. Suppose the significance level is 0.02, the test statistic is positive, and the statistical decision is to FTR Ho. If we redo the test at ? = 0.05, our statistical decision would be: ---Select--- There is not enough information to make a decision at 0.05 FTR Ho at ? = 0.05 Reject Ho at...
