Suppose there is a claim that a certain population has a mean, µ, that is different than 5. 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, H,, as follows. Ho: u= 5 H: u #5 Suppose you also know the following information. The value of the test statistic based on the sample is -1.526 (rounded to 3 decimal places). The p-value is 0.127 (rounded to 3 decimal places). (a) Complete the steps below for this hypothesis test. Standard Normal Distribution 04 Step 1: Select one-tailed or two-tailed. O One-tailed O Two-tailed 03+ Step 2: Enter the test statistic. (Round to 3 decimal places.) 02+ Step 3: Shade the area represented by the p-value. 0.1+
