A sample of 18 items provides a sample standard deviation of 9.5. Test the following hypotheses using a = 0.05. What is your conclusion? Ho: ² ≤ 50 H₂:0² > 50 Use the p-value approach. Find the value of the test statistic. Find the p-value. (Round your answer to three decimal places.) p-value = State your conclusion. O Reject Ho. We conclude that the population variance is greater than 50. O Do not reject Ho. We conclude that the population variance is greater than 50. O Reject Ho. We conclude that the population variance is not greater than 50. O Do not reject Ho. We conclude that the population variance is not greater than 50. Use the critical value approach. Find the value of the test statistic. State the critical values for the rejection rule. (Round your answers to three decimal places. If the test is one-tailed, enter NONE for the unused tail.) test statistic s test statistic 2 State your conclusion. O Reject Ho. We conclude that the population variance is greater than 50. O Do not reject Ho. We conclude that the population variance is greater than 50. O Reject Ho. We conclude that the population variance is not greater than 50. O Do not reject Ho.
