Question

Consider the following hypothesis test: H0: μ = 15 Ha: μ ≠ 15 A sample of 50 provided a sample mean of 14.18. The population standard deviation is 5. a. Compute the value of the test statistic (to 2 decimals). b. What is the p-value (to 4 decimals)? c. Using α = .05, can it be concluded that the population mean is not equal to 15? Select Yes No Answer the next three questions using the critical value approach. d. Using α = .05, what are the critical values for the test statistic? (+ or -) e. State the rejection rule: Reject H0 if z is Select greater than or equal to greater than less than or equal to less than equal to not equal to the lower critical value and is Select greater than or equal to greater than less than or equal to less than equal to not equal to the upper critical value. f. Can it be concluded that the population mean is not equal to 15? Select Yes No
