3. Six percent of the computer chips produced by Cheapo Chips are defective. Each month a random sample
of 200 chips manufactured in that month is selected. Let X= the number of defective chips in the sample.
(a) Calculate the mean and standard deviation of X.

(b) Find the probability that 8 or fewer chips in a sample of 200 are defective.
p(xg8)%3D(200,0.06,8)=0.1470
(c) To reduce the percentage of defective chips, the company contracts with a new supplier for some
important components. In the next month, the sample of 200 chips has only 8 defective ones. Can the
company conclude that the new components have reduced the rate of defective chips produced?
Explain.
