Question

A sample of 31 observations is selected from a normal population. The sample mean is 30, and the population standard deviation is 6. Conduct the following test of hypothesis using the 0.05 significance level.

H₀: μ ≤ 27

H₁: μ > 27

Is this a one- or two-tailed test?

multiple choice 1

"One-tailed"—the alternate hypothesis is greater than direction.
"Two-tailed"—the alternate hypothesis is different from direction.

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

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

What is your decision regarding H₀?

multiple choice 2

Do not reject
Reject

e-1. What is the p-value? (Round your answer to 4 decimal places.)

e-2. Interpret the p-value? (Round your answer to 2 decimal places.)
