a data set and drawing x and R charts in MS Excel.

the instructions

• The control limit is 99.73%, the population standard deviation is 17, and the population mean is 73.
• Calculate the UCLx and LCLx for the x chart.
• Your sample size is 10.
• Use the RANDBETWEEN function to generate random numbers between 40% more than the UCL and 40% less than the LCL. Your table will generate random and different numbers but should look like the following table. However, in your case, there must be 20 samples, not 5.
