Suppose there is a dalm that a certain population has a mean, that is greater than 8. You want to test this calm. To do so, you collect a large random sample from the population and perform a hypothesis test at the 0.05 level of significance. To start this test, you write the null hypothesis and the alternative hypothesis H. as follows. Hu=8 H:> Suppose you also know the following information The critical value is 1.645 (rounded to 3 decimal places). The value of the test statistic is 2.588 (rounded to 3 decimal places). (a) Complete the steps below to show the rejection region's) and the value of the test statistic for this test. Standard Normal Distribution Step 1: Soka one-tailed a two-talled One-tailed O Tweed Step 2: Em the trial valus) (round to deal places) Step 3: Enter the test (lure to donat lacus 수 (b) Based on your answer to part (a), choose the correct statement. The value of the test statistic lies in the rejection region. The value of the test statistic doesn't lie in the rejection region ? (c) Based on your answer to part (b), which statement below is true at the 0.05 level of significance The na hypothes should be resected The nut hypothes should not be reacted ?
