A sample of 20 items provides a sample standard deviation of 9.5. Test the following hypotheses using a = 0.05. What is your conclusion? Ho: 0² < 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.
