Question: A sample of 16 items provides a sample standard deviation of 9.5. Test the following hypotheses using a = .05. Ho: 0250 2 Ha

A sample of 16 items provides a sample standard deviation of 9.5. Test the following hypotheses using a = .05. Ho: 0250 2 Ha > 50 a. Calculate the value of the test statistic (to 2 decimals). 27.08 The p-value is between .025 and .05 + What is your conclusion? Conclude that the population variance is greater than 50 b. Repeat the hypothesis test using the critical value approach. Round critical value to 3 decimal places. What is the rejection rule for this hypothesis test? Reject Ho if x 2 greater than or equal to + What is your conclusion? 7.261 Conclude that the population variance is greater than 50
