Suppose there is a claim that a certain population has a mean, μ, that is less than 7. You want to test this claim. To do so, you collect a large random sample from the population and perform a hypothesis test at the 0.10 level of significance. To start this test, you write the null hypothesis H and the alternative hypothesis H₁ as follows. H₁: μ = 7 H₁: μ<7 Suppose you also know the following information. The critical value is -1.282 (rounded to 3 decimal places). The value of the test statistic is -0.942 (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: Select one-tailed or two-tailed. O One-tailed O Two-tailed Step 2: Enter the critical value(s). (Round to 3 decimal places.) Step 3: Enter the test statistic. (Round to 3 decimal places.) (b) Based on your answer to part (a), choose the correct statement. O The value of the test statistic lies in the rejection region. The value of the test statistic doesn't lie in the rejection region. 04 X 03- 02+ 0.1 + X 5 (c) Based on your answer to part (b), which statement below is true at the 0.10 level of significance? O The null hypothesis should be rejected. The null hypothesis should not be rejected. X 5
