Homework Answers
Standard deviation cannot be calculated with the given information. Because to calculate standard deviation of a process we need an additional information about the sample size too.

Suppose that material hardness is normally distributed with a mean of 52 and a standard deviation of 1. Specification limits for hardness are from 45 to 55. What is the fraction defective? What value for the process mean will minimize the fraction defective? When the fraction defective is 0.0027 this corresponds to what PPM?

1) A process for manufacturing an electronic component yields items of which 1% are defective. A quality control plan is to select 100 items from the process, and if none are defective, the process continues. Use the normal approximation to the binomial to find (a) the probability that the process continues given the sampling plan described; (b) the probability that the process continues even if the process has gone bad (i.e., if the frequency of defective components has shifted to...
