Espa Suppose there is a claim that a certain population has a mean, u, that is different than 6. 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 0.05 level of significance. To start this test, you write the null hypothesis, /, and the alternative hypothesis, //, as follows. Ho: H-6 Suppose you also know the following information. The value of the test statistic based on the sample is 2.044 (rounded to 3 decimal places). The p-value is 0.041 (rounded to 3 decimal places). (a) Complete the steps below for this hypothesis test. Standard Normal Distribution Step 1: Select one-tailed or two-tailed. o One-tailed Two-tailed Step 2: Enter the test statistic. ( Round to 3 decimal places.) Step 3: Shade the area represented by the p value. (b) Based on your answer to part (a), which statement below is true? Since the p-value is less than (or equal to) the level of significance, the null hypothesis is rejected. Since the p-value is less than (or equal to) the level of significance, the null hypothesis is not rejected. Since the p-value is greater than the level of significance, the null hypothesis is rejected. Since the p-value is greater than the level of significance, the null hypothesis is not rejected
