Suppose that you are monitoring the weight of pet food packages down a automatic production line. Which chart will you use? Variable chart or attribute charts? Why?

Solution

control chart for continuous chart(R-chart and X-bar chart) we should use

suppose weight of pet food packages down a automatic production line then after a certain point of time it exceeds the control limits (UCL or LCL) then it indicates after that all products are fails to meet the specification.

here we use give a bound for Sample Ranges by R-chart if Rchart is in control then we can chexk through X-bar chart.
