Question: consider the following hypothesis test h 0 15 h...

Question details

Consider the following hypothesis test: H 0: = 15 H a: 15 A sample of 40 provided a sample mean of 14.33. The population standard deviation is 7. a. Compute the value of the test statistic (to 2 decimals). (If answer is negative, use minus “-“ sign.) -0.60 b. What is the p-value (to 4 decimals)? -1.2105 c. Using = .05, can it be concluded that the population mean is not equal to 15? Answer the next three questions using the critical value approach. d. Using = .05, what are the critical values for the test statistic (to 2 decimals)? ± e. State the rejection rule: Reject H 0 if z is the lower critical value and is the upper critical value. f. Can it be concluded that the population mean is not equal to 15?
