You're installing a new media center for a client. It's 08/03, the planned completion date, but the project isn't finished. The client wants to know when the project will be completed. Task | Planned Start Date | Planned End Date | Actual Start Date | Actual End Date Final contracts signed | 06/15 | 06/22 | 06/15 | 07/13 Order and receive equipment | 06/22 | 06/29 | 07/13 | 07/20 Run wiring | 06/29 | 07/06 | 07/20 | 07/27 Install equipment | 07/06 | 07/13 | 07/27 | 08/03 Train customer on software | 07/13 | 08/03 | | ?

Problem: A large company is considering paying for employees to take part in a weight loss program. The company decides that if the average weight loss of a sample group is at least 20 pounds, the company will contract with the weight loss program and pay all expenses for the future employees that participate. The company pays for 20 randomly selected participants to participate in the trial run. The weights of the 20 participants are recorded before the trial begins. After eight months of the participants being on the program, their weights are recorded. The level of significance for the problem is .05. Weight Before Program will be Sample Weight After Program will be Sample 2. Setting the problem up as Sample 1 – Sample 2, write the null and alternative for the problem. (.1)
