i need to find parts 1-4:

1) what is the value of x?

=x= _____mm (round your response to two decimal places)

2) what is the value of r?

r= ____ mm (round your response to two decimal places)

3) what are the UCL-x and LCL-x using 3 sigma?

- upper control limit (UCLx-)= ___ mm (round response 2 decimal places)

-lower control linit (LCLx-)= ___ mm (round response 2 decimal places)

4) whatxare the UCLr and LCLr using 3 sigma?

- upper control limit (UCLr)= ___ mm (round response 2 decimal places)

-lower control limit (LCLr)= ___ mm (round response 2 decimal places)

thanks!

(4) Mhat in for vate of on. Auto pistons at Wemming Chung's plant in Shanghal are produced in a forging process, and the diameter is a citical 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: a) What is the value of x ? x=mm (round your response to two decimal places)
