When a production line is properly adjusted, it is found that 4% of the mechanical components produced are defective. Occasionally settings go out of adjustment, and more defectives are produced. A sample of 10 components is examined and the number of defectives is counted. a. What distribution applies to the number of defectives? b. What are the null hypothesis and the alternative hypothesis? c. If the level of significance is set at 1%, how many defectives can be allowed in the sample before any action is taken?
