Frito-Lay keeps track of the sample mean‚ the type of chart we are going to make is called and X bar chart. They must also examine the charts for a run‚ a string of results on one side of the mean. If an ongoing issue is hard to resolve in-house‚ the plant manager may call in a team of Frito-Lay experts. The teams are called “star fleet teams” and they are based on

As part of a designed study‚ 15 accountants were randomly selected from each of the four leadership style groups. Each accountant was asked to rate the degree to which their subordinates performed substandard field work on a 10-point scale -- called the "substandard work scale". The objective is to compare the mean substandard work scales
