A & C\ State your Test Decision & Basis for the Decision: This is Step 5 of a hypothesis test and state what values are you comparing to make your decision. Do not state all the steps of a HT
B & D\ Interpretation\Analysis of Results: This is Step 6 of a HT – application of results to context.
It is suggested you read the Survey Question (from the Survey Question sheet of the Survey Data File) for the response variable being tested.
Whether you reject or fail to reject, the issue then becomes what is some plausible reason or explanation or interpretation for the outcome the test produced?
Responses should be concise, clear, and organized.
You are not asked to state H0and H1,but it will help you answer B & D.
