bestions Exercise 09.23 (Population Mean: Sigma Unknown) Que Hint(s) Chec Consider the following hypothesis test: O Ho: p 12 A sample of 25 provided a sample mean z = 14 and a sample standard deviation s = 4.32. a. Compute the value of the test statistic (to 2 decimals). 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 greater than or equal to the critical value of (to 3 decimals). Can you conclude that the population mean is greater than 12? Yes Hide Feedback
