A sample of 36 observations is selected from a normal population. The sample mean is 12, and the population standard deviation is 3.
Conduct the following test of hypothesis using the 0.01 significance level.
H0: μ ≤ 10 H1: μ > 10
a. Is this a one- or two-tailed test? multiple choice 1 One-tailed test Two-tailed test
b. What is the decision rule? multiple choice 2 Reject H0 when z > 2.326 Reject H0 when z ≤ 2.326
c. What is the value of the test statistic?
d. What is your decision regarding H0? multiple choice 3 Reject H0 Fail to reject H0
e-1. What is the p-value? e-2. Interpret the p-value?
