Consider the following hypothesis test: He: µ =18 A sample of 48 provided a sample mean = 17 and a sample standard deviation s = 4.8. Enter negative values as negative numbers. H.: µ # 18 a. Compute the value of the test statistic (to three decimal places). -1.443 O b. Use the t distribution table (Table 2 in Appendix B) to compute a range for the p-value (to two decimal places). p-value is between 0.10 and 0.16 8 C. At a = 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 equal to 2.012 or t is greater than or equal to 2.012 v What is your condlusion (to three decimal places)? t = -1.443 do not reject Ho.
