Question

A sample of 31 observations is selected from a normal population. The sample mean is 23, and the population standard deviation is 2. Conduct the following test of hypothesis using the 0.10 significance level.

H₀: μ ≤ 22

H₁: μ > 22

Is this a one- or two-tailed test?

multiple choice 1

One-tailed test
Two-tailed test

What is the decision rule?

multiple choice 2

Reject H₀ when z > 1.282
Reject H₀ when z ≤ 1.282

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

What is your decision regarding H₀?

multiple choice 3

Reject H₀
Fail to reject H₀

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

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