A manufacturer claims to produce only 5% defective units. A bulk buyer of these units selects 100 and finds ten defective. a. Using the chi - squared goodness-of-fit test, determine whether there is reason to doubt the manufacturer's claim. Use α = 0.05. b. Compare the answer with part a, which is obtained by using the approximation method discussed in Chapter 9 to test the null hypothesis that the true proportion of defective items is 0.05.
