A continuous production line is producing electrical components. When all adjustments are correct, 3.2% of the components from the line are defective. A sample of 480 components is taken every four hours, and the number of defectives is counted. If there are more than 21 defectives in the sample, extensive adjustments will be made.

Use Excel. This is the same problem as number 5, except that that problem was done using a normal approximation.

a) State the null hypothesis and alternative hypothesis.

b) What is the observed level of significance if there are 22 defectives in the sample?

c) If the probability that a component will be defective has increased to 6.0%, what is the probability of a Type II error?
