Cp and Cpk? Explain if the new implementations are helping the process or not. 6.1.3 is before, 6.1.4 is the data after the new implementations were made.

more fun now. To make further improvements, the owners of Hop Scotch have decided to change how the servers serve cus- tomers. In the past, each server was assigned a section of the parking lot. But now, observing the activities in the restau- rant parking lot, the owners see that the lot does not fill up evenly; some sections fill up first, especially when a group comes in to be served all at once. This unevenness often over- whelms a particular server while another server has very few cars to wait on. Under the new program, servers will handle any area of the parking lot, serving cars on a first-come, first- served basis. ASSIGNMENT Use the data in Table C6.1.4 (on page 234) to calculate the process capability, Cp, and Cpk. Do the new rules help?
