Discuss the following:
Q1: The following information is available.
H0: µ ≤ 10
H1: µ > 10
The sample mean is 12 for a sample of 36. The population standard deviation is 3. Use the .02 significance
Q2: H0: π = .40
H1: π ≠ .40

a. State the decision rule.
b. Compute the value of the test statistic.
c. What is your decision regarding the null hypothesis?
