Consider the following hypotheses: Ho: μ ≤ 480 HA: μ > 480 Find the p-value for this test based on the following sample information.

Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. H0: p = 0.2 versus H1: p > 0.2 n = 100; x = 25; α = 0.05 Calculate the test statistic, z0. z0 = 1.25 (Round to two decimal places as needed.) Identify the P-value. P-value = (Round to three decimal places as needed.) Choose the correct result of the hypothesis test for the P-value approach below. A. Reject the null hypothesis, because the P-value is greater than α. B. Do not reject the null hypothesis, because the P-value is less than α. C. Reject the null hypothesis, because the P-value is less than α. D. Do not reject the null hypothesis, because the P-value is greater than α.

Find the P-value for the indicated hypothesis test with the given standardized test statistic. Decide whether to reject Ho for the given level of significance ̑. Right-tailed test with test statistic z = 0.67 and ̑ = 0.05. P-value: (Round to four decimal places as needed.) Hint: Keep in mind that the P-value depends on the type of test. Left-tailed test: P-value = Area (where Area is the number from the table) Right-tailed test: P-value = 1 - Area Two-tailed test: P-value = 2 * Area Compare P with ̑ and then state your conclusion: Fail to reject Ho Reject Ho
