Consider the following hypothesis test.
H0: μ ≤ 50 |
Ha: μ > 50 |
A sample of 60 is used and the population standard deviation is 8. Use the critical value approach to state your conclusion for each of the following sample results. Use α = 0.05.
(Round your answers to two decimal places.)
(a)x = 52.5
Find the value of the test statistic.
State the critical values for the rejection rule. (If the test is one-tailed, enter NONE for the unused tail.)
test statistic≤
test statistic≥
State your conclusion.
Reject H0. There is insufficient evidence to conclude that μ > 50.Do not reject H0. There is sufficient evidence to conclude that μ > 50. Reject H0. There is sufficient evidence to conclude that μ > 50.Do not reject H0. There is insufficient evidence to conclude that μ > 50.
(b)x = 51 Find the value of the test statistic.
State the critical values for the rejection rule. (If the test is one-tailed, enter NONE for the unused tail.)
