Question: As an extension to problem 8-2, have each team member generate an additional 3 samples of five, only this time by rolling a single die

As an extension to problem 8-2, have each team member generate an additional 3 samples of five, only this time by rolling a single die rather than a pair of dice. This procedure will result in an additional 15 samples for the team. Plot these 15 samples on the original charts. Be certain that the control limits and centerlines do not change. Then answer the following questions.
a. Is there evidence to suggest that the last 15 samples came from a process different from the first 25? Explain
b. Is the process of the single die different with respect to variance, mean, or both? How can you tell?
