i need C,D, and E . i need to show work how i got the answer for all those 3 parts

Auto pistons at Wermiog Chung's plant in Shanghai are produced in a forging process, and the diameter is a critical factor that must be controlled. From sample sizes of 10 pistons produced each day, the mean and the range of this diameter have been as follows: DAY MEAN (MM) RANGE (MM) 1 156.9 4.2 2. 153.2 4.6 3 153,6 4.1 4 155.5 5.0 5 156.6 4.5 c. What are the UCL, and LCLg , using 30? Plot the data. d. What are the UCL, and LCLR, using 30? Plot the data. e. If the true diameter mean should be 155 mm and you want this as your center (nominal) line, what are the new UCL, and LCL
