The Consultant Suspiciously Eyed the C-Chart That Chickenverks Used to Monitor

Multiple Choice

The consultant suspiciously eyed the c-chart that Chickenverks used to monitor the number of broken eggs in each 100 egg carton. "You know you really should be using a p-chart," the consultant commented with an air of superiority. "What's the difference between a p-chart and a c-chart in this application?" the long time Chickenverks employee asked with an obvious edge to his voice. "Well," the consultant replied, "the difference is:

A) the width of the three sigma limits for the c-chart is 100 times greater than those of the p-chart."
B) the three-sigma p-chart will catch problems earlier than the three sigma c-chart."
C) the three-sigma c-chart will catch problems earlier than the three sigma p-chart."
D) well, OK, you got me. The charts will look and behave the same for all practical purposes."
