A critical parameter is monitored on a process, and measurments yield data from mean and range computations

During every sample, 5 observations are recorded. The overall mean for the process is 22 and the average range is 5.5

Given the table of contro chart factors, compute the upper control limit for the 3-stigma X-bar chart. round answer to one decimal place

During every sample period, 5 observations are recorded. The overall mean for the process is 22 and the average range is 5.5. Given the table of contro chart factors, compute the upper control limit for the 3-sigma X- bar chart. Round your answer to one decimal place, if applicable.
