Two different types of injection-molding machines are used to form plastic parts. A part is considered defective if it has excessive shrinkage or is discolored. Two random samples, each of size 300, are selected, and it was found that p1 -0.05 and p2 -0.01. Is it reasonable to conclude that both machines produce the same fraction of defective parts, using alpha = 0.057 Determine the sample size needed to detect this difference with a probability of at least 0.9 Use...

Two different types of injection-molding machines are used to form plastic parts. A part is considered defective if it 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. What type of hypothesis test should you use to determine if both machines produce the same fraction of defective parts? Group of...

Two different types of injection-moulding machines are used to form plastic parts. A part is considered defective if it has excessive shrinkage or is discolored. Two random samples, each of size 300, are selected, and 20 defective parts are found in the sample from machine 1, and 8 defective parts are found in the sample from machine 2. Construct a 99% lower bound on the difference in the two fractions (p1-p2). Please report your answer to 3 decimals.
