Given the following hypotheses:

H₀ : 22

H₁ : > 22

A random sample of 75 observations is selected from a normal population. The sample mean was 24 and the sample standard deviation was 4. Using the 0.10 significance level:

a.State the decision rule. (Round the final answer to 3 decimal places.)

(Reject or Do not reject) H₀ if t > _______.

b.Compute the value of the test statistic. (Round the final answer to 3 decimal places.)

Value of the test statistic _______

c.What is your decision regarding the null hypothesis?

(Reject or Accept) H₀. At the 0.01 significance level, the mean(is or is not) greater than 22.
