The pharmaceutical company has recently introduced a new medication and established a dedicated production line for the creation of a particular size of the drug's pills. The diameter of the pills was deemed an important factor in terms of quality control. By collecting 10 pills produced daily, the company calculated the average and range of the pill diameter over the course of 5 days and closely monitored the results, as shown:

Day	Mean (millimeter)	Range (millimeter)
1	156.9	4.2
2	153.2	4.6
3	153.6	4.1
4	155.5	5
5	156.6	4.5

Determine and Construct the control chart/charts.

Can you conclude that the process of producing the drug's pills is in control?

Assumed that the manufacturing estimated process that produces the drug's pills is centered at 155.16 millimeters and has a standard deviation of 0.46 millimeters. If the specification for the pill's diameter is 155 ± 2 millimeters, does the process capable of producing within the specification limits? (Support your answer based on Cp and Cpk)

Based on Parts B and c, how can you describe and explain the overall process of producing the drug's pills?
