Consider the following hypothesis test: Ho : μ < 12 H₁: > 12 A sample of 25 provided a sample mean = 14 and a sample standard deviation s = 4.32. a. Compute the value of the test statistic (to 2 decimals). 2.31 b. Use the t distribution table (Table 2 in Appendix B) to compute a range for the p-value. The p-value is between 0.01 and 0.025 c. At a = 0.05, what is your conclusion? Reject null hypothesis d. What is the rejection rule using the critical value? (Use a = 0.05.) Reject Ho if t is equal to : I the critical value of Can you conclude that the population mean is greater than 12? No Hide Feedback Partially Correct Icon Key 0.015 (to 3 decimals). Hint(s) Check My W
