A sample of 38 observations is selected from a normal population. The sample mean is 26, and the population standard deviation is 6. Conduct the following test of hypothesis using the 0.05 significance level.

H₀ : 23

H₁ : > 23

Is this a one- or two-tailed test?

"One-tailed"-the alternate hypothesis is greater than direction.

"Two-tailed"-the alternate hypothesis is different from direction.

b.	What is the decision rule? (Round your answer to 3 decimal places.)

H₀, when z >

c.	What is the value of the test statistic? (Round your answer to 2 decimal places.)

Value of the test statistic

What is your decision regarding H₀?

Do not reject

Reject

There is

evidence to conclude that the population mean is greater than 23.

e.	What is the p-value? (Round your answer to 4 decimal places.)

p-value
