Question

You may need to use the appropriate appendix table or technology to answer this question. Consider the following hypothesis test. H0: μ = 15 Ha: μ ≠ 15 A sample of 50 provided a sample mean of 14.09. The population standard deviation is 3. (a) Find the value of the test statistic. (Round your answer to two decimal places.) (b) Find the p-value. (Round your answer to four decimal places.) p-value = (c) At α = 0.05, state your conclusion. Reject H0. There is sufficient evidence to conclude that μ ≠ 15. Reject H0. There is insufficient evidence to conclude that μ ≠ 15. Do not reject H0. There is sufficient evidence to conclude that μ ≠ 15. Do not reject H0. There is insufficient evidence to conclude that μ ≠ 15. (d) State the critical values for the rejection rule. (Round your answers to two decimal places. If the test is one-tailed, enter NONE for the unused tail.) test statistic ≤ test statistic ≥ State your conclusion. Reject H0. There is sufficient evidence to conclude that μ ≠ 15. Reject H0. There is insufficient evidence to conclude that μ ≠ 15. Do not reject H0. There is sufficient evidence to conclude that μ ≠ 15. Do not reject H0. There is insufficient evidence to conclude that μ ≠ 15.
