A manufacturing process produces 5% defective items. What is the probability that in a sample of 60 items: a. 11% or more will be defective? (Round the z-value to 2 decimal places and the final answer to 4 decimal places.) Probability b. less than 2% will be defective? (Round the z-value to 2 decimal places and the final answer to 4 decimal places.) Probability c. more than 11% or less than 2% will be defective? (Round the z-value to 2 decimal places and the final answer to 4 decimal places.) Probability

Step 1
First, we need to find the mean and standard deviation of the number of defective items in a sample of 60 items. Since the manufacturing process produces 5% defective items, the mean (μ) and standard deviation (σ) can be calculated as follows: μ = n * p = 60 * Show more…
