A local retailer is trying to cut down on shipping costs. They are debating between FedEx or UPS as their primary shipping service. A random sample of 33 packages that need to be shipped are taken. For each of the 33 packages, the shipping cost was estimated for both FedEx and UPS; a new "diff" variable was calculated as FedEx minus UPS. You are asked to run a hypothesis test to see if there is a significant difference, on average, in shipping cost between FedEx and UPS for all packages shipped by the local retailer. Complete the following problems, working through the steps of a hypothesis test. Question 3 Subquestions 3.a Step 1: Provide the hypotheses and define the parameter in context.
