Consider the chemical process yield data in Exercise 3.9. Calculate the sample average and standard deviation. The probability distribution of x is f(x) = ke–x,0 ≤ x ≤ . Find the appropriate value of k. Find the mean and variance of x. A sample of 100 units is selected from a production process that is 1% nonconforming. What is the probability that pˆ will exceed the true fraction nonconforming by k standard deviations, where k = 1, 2, and 3? A textbook has 500 pages on which typographical errors could occur.
