a) Is it appropriate to use the normality approximation? (b) Using n = 20 and α = 0.05, determine the threshold for the number of bad samples and establish the associated decision rule. (c) If the actual defective rate of the product is 0.1, try to find the error probability value of Type II. Do you think the law established in (b) is satisfactory? Suggest how you would improve the testing process.
