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, while 12 defective parts are found in the sample from machine 2. Is it reasonable to conclude that both machines produce the same proportion of defective parts, using a = 0.05? Answer by finding the P-value for the test. Round your answer to 3 decimal places. P-value - i 1.445 It is reasonable to conclude that both machines produce the same proportion of defective parts.
