19. According to one of the Western Electric rules for quality control, a produced item is considered conforming if its measurement falls within three standard deviations from the target value. Suppose that the process is in control so that the expected value of each measurement equals the target value. What percent of items will be considered conforming, if the distribution of measurements is
(a) Normal(μ, σ)? (b) Uniform(a, b)?

Each item produced by a production system goes through a quality inspection process to be classified as non-defective (ND), partially defective (PD), or totally defective (TD). Over the past several years, category percentages for a certain item produced by this system have stabilized at 85% non-defective (ND), 10% partially defective (PD), and 5% totally defective (TD). The company has purchased a new machine for producing this item. A sample of size 200 items produced by the new machine yielded 180...

According to Mars, Inc., 20% of all M&Ms produced are blue. One bag of 50 M&Ms represents the sample for this problem. The sample data can be used to perform a two-sided hypothesis test to test whether 20% of all M&Ms are blue. In one bag of 50 M&Ms, there are 14 blue M&Ms. Use this data to test whether 20% of all M&Ms are blue.
