Question 364399: A foreman at a large plant estimates defective parts about 1% of the time. If the plant produces 30,000 parts in a week, what is the standard deviation (to the nearest tenth) for the number of defective parts? Answer by robertb(5830) (Show Source):
You can put this solution on YOUR website! This is a binomial experiment with n = 30000, p = 0.01, and q = 1-p = 0.99. The mean is and the standard deviation is , to 4 decimal places.
