Procedure for Performing a Hypothesis Test:

• Specify and which are to be tested.
• Select a significance level of the test.

(Usually α = 0.01, 0.05, 0.10)

• Collect Sample Data.
• Calculate the test statistic using information from the sample.
• Calculate the associated p-value for the test.
• Make a decision based on the p-value.

If p-value < α, reject

If p-value ≥ α, do not reject .
