Efficient manufacturing: Efficiency experts study the processes used to manufacture items in order to make them as efficient aspossible. One of the steps used to manufacture a metal clamp involves the drilling of three holes. In a sample of 50 clamps, themean time to complete this step was 53.3 seconds. Assume that the population standard deviation is a = 8 seconds. Round thecritical value to no less than three decimal places.Part: 0 / 2Part 1 of 2(a) Construct a 99.8% confidence interval for the mean time needed to complete this step. Round the answer to at least onedecimal place.A 99,8% confidence interval for the mean is <<Part: 1/2Part 2 of 2(b) Find the sample size needed so that a 99.9% confidence interval will have margin of error of 1.5.A sample size of is needed in order to obtain a 99.9% confidence interval with a marginerror of 1.5. Round the sample size up to the nearest integer.

From the provided information,Sample size (n) = 50Sample mean (x̄) = 53.3Population standard…

6 X 01:13:24 eBook Quality Progress, February 2005, reports on improvements in customer satisfaction and loyalty made by Bank of America. A key measure of customer satisfaction is the response (on a scale from 1 to 10) to the question: "Considering all the business you do with Bank of America, what is your overall satisfaction with Bank of America?" Here, a response of 9 or 10 represents "customer delight." Suppose that the survey selected 480 customers. Assume that 45% of Bank of America customers would currently express customer delight. That is, assume p = .45. (a) Find the probability that the sample proportion obtained from the sample of 480 Bank of America customers would be within three percentage points of the population proportion. That is, find P(.42 ≤ § ≤ .48). (Round your answer to 4 decimal places. Do not round intermediate values. Round z-value to 2 decimal places.) P(.42 ≤ ≤.48)
