A fabric manufacturer employs a control chart to monitor stained fabric rolls in their production runs. The results of their process were inspected for 20 days taking the day's production as a sample, giving the results shown in the table below: (Image attached) Use this data to construct a control chart for stained rolls of fabric. Is the process under control? What limits would you recommend to control future production? Do not use an average size of the number of rolls.

A pharmaceutical manufacturer forms tablets by compressing a granular material that contains the active ingredient and various fillers. The force in kilograms (kg) applied to the tablet varies a bit and follows the Normal distribution with mean 11.5 kg and standard deviation 0.2 kg. The process specifications call for applying a force between 11.2 and 12.2 kg. i. What percent of tablets are subject to a force that meets the specifications? ii. The manufacturer adjusts the process so that the mean force is at uie center of the specifications, u = 11.7 kg. The standard deviation remains 0.2 kg. What percent now meets the specifications? iii. Calculate the 25th percentile (P2s) and the 75th percentile (P7s) of the distribution.
