# Question: A rectangular piece of metal of width W and length

A rectangular piece of metal of width W and length L is cut from a plate of thickness T. If W, L, and T are independent random variables with means and standard deviations as given here and the density of the metal is 0.08 g/cm3, what would be the estimated mean and standard deviation of the weights of pieces produced by this process?

Perform a process capability analysis using x and R charts for the data in Exercise 6.7. We wish to estimate a two-sided natural tolerance interval that will include 99% of the values of a random variable with probability 0.80.
