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?
Answer to relevant QuestionsPerform 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. If nothing is known about the distribution of the random variable, how large should ...Find the sample size required to construct an upper nonparametric tolerance limit that contains at least 95% of the population with probability at least 0.95. How would this limit actually be computed from sample data? Consider the loan processing cycle time data in Exercise 8.15. Set up an EWMA control chart for monitoring this process using = 0.1. Does the process seem to be in statistical control? x p50 18.05; p84 20.53; ...Apply the scale CUSUM discussed in Section 9.1.8 to the concentration data in Exercise 9.8. Exercise 9.8
