You may need to use the appropriate appendix table or technology to answer this question.

Consider the following hypothesis test.

 H0: μ ≤ 25 Ha: μ > 25

A sample of 40 provided a sample mean of 26.2. The population standard deviation is 6.

(a) Find the value of the test statistic. (Round your answer to two decimal places.)

p-value = ?

(c) At α = 0.01,state your conclusion.

a) Reject H0. There is sufficient evidence to conclude that μ > 25.

b) Reject H0. There is insufficient evidence to conclude that μ > 25.

c) Do not reject H0. There is sufficient evidence to conclude that μ > 25.

d) Do not reject H0. There is insufficient evidence to conclude that μ > 25.

(d) State the critical values for the rejection rule. (Round your answer to two decimal places. If the test is one-tailed, enter NONE for the unused tail.)

test statistic≤ ( ?    )

test statistic≥ ( ?    )

a) Reject H0. There is sufficient evidence to conclude that μ > 25.

b) Reject H0. There is insufficient evidence to conclude that μ > 25.

c) Do not reject H0. There is sufficient evidence to conclude that μ > 25.

d) Do not reject H0. There is insufficient evidence to conclude that μ > 25.  #### Earn Coins
