Question: The competing hypotheses for a particular hypothesis test are as follows:

Ho: µ ≤ 2500 Ha: > 2500

A random sample of size 36 is taken from the target population. The sample mean is 2525. Assume the population standard deviation is known to be 120. Using a significance level of.01, follow the four steps below to test the null hypothesis:

Step 1: State the null and alternative hypotheses.

Step 2: Choose a test statistic and use the significance level to establish a decision rule. Step 3: Compute the value of the test statistic.

Step 4: Apply the decision rule and make your decision.
