Two different types of injection-molding machines are used to form plastic parts. A part is considered defective if has excessive shrinkage or is discolored. Two random samples, each of size 300, are selected, and 15 defective parts are found in the sample from machine 1, and 8 defective parts are found in the sample from machine 2. Construct a 95% confidence interval on the difference in the two fractions defective O a. Cl on the difference: -0.0094 <= p1 - p2 <= 0.074 O b. Cl on the difference: -0.0054<=p1 - p2 <= 0.034 O c. Cl on the difference: -0.0074 <=p1 - p2 <= 0.054 O d. None among the choice
