[9:48 PM, 5/7/2020] Saria: A sample of 31 observations is selected from a normal population. The sample mean is 11, and the population standard deviation is 3. Conduct the following test of hypothesis using the 0.05 significance level.

H0: μ ≤ 10

H1: μ > 10

Is this a one- or two-tailed test?

One-tailed test
Two-tailed test

What is the decision rule?

Reject H0 when z > 1.645
Reject H0 when z ≤ 1.645

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


What is your decision regarding H0?

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.)
