Questions Exercise 09.24 (Population Mean: Sigma Unknown) 1, O Consider the following hypothesis test: Ho: / = 18 Ha: u # 18 A sample of 48 provided a sample mean & = 17 and a sample standard deviation s = 4.5. If necessary, round your answers to two decimal places. Enter negative values as negative numbers. a. Compute the value of the test statistic. X b. Use the t distribution table (Table 2 in Appendix B) to compute a range for the p-value. p-value is between x and X C. At & = 0.05, what is your conclusion? p-value is greater than 0.05, do not reject Ho. d. What is the rejection rule using the critical value? Reject Ho if t is less than or equal to -2.012 or t is greater than or equal to 2.012 v What is your conclusion? do not reject Ho. Hide Feedback Partially Correct
