Assuming that these data were collected when the manufacturing process was believed to be operating in control, develop the R chart.
Compute the upper and lower control limits for the R chart. (Round your answers to two decimal places.)
Assuming that these data were collected when the manufacturing process was believed to be operating in control, develop the x chart.
Compute the upper and lower control limits for the x chart. (Round your answers to two decimal places.)
