Which hypothesis do I accept and reject, please make it clear

Case #1: (30 points): A branch manager of Wonderful Bank devised a new process designed to reduce customer wait times at her branch. The branch manager received permission from the bank president to test her new process against the existing process. The branch manager contacted you to design and conduct the proper test. She would like the analysis to be set up to determine if the wait times using her new process are shorter than under the existing process.

Using Version 1 of the SSP, complete the following:

a. Complete the preliminary Steps of the SSP (Steps 1 through 4). What CL do you recommend for the client? Be sure to discuss the reason for your recommendation.

b. Analyze the data and report your results to the branch manager. Note: wait times are recorded in minutes. As you can see, data were collected on wait times using the old process (labeled WT 1). Next, the new process was installed, and after a few weeks, a second sample was collected (labeled WT 2). Both samples used a random collection design.

c. Analyze Wait Times from the old process versus Wait Times from the new process.

d. Discuss your findings and conclusions. Do you think the test was successful in the eyes of your client? What will your client recommend to the Bank President?

e. Finally, do you think the bank president will allow the manager to install the new process? On what rationale do you base your opinion?
