Determine the fraction defective in each sample (Round your answers to 4 decimal places.) Sample 1 2 Fraction defective 0.0211 0.0105 0.0316 0.0421 3 4 b. If the true fraction defective for this process is unknown, what is your estimate of it? (Round your answer to 1 de Estimate 2.6 % Homework 1 Saved Help e. What alpha risk would control limits of 0470 and 0056 provide? (Round your intermediate calculations to 4 decimal places. Round your "z" value to 2 decimal places and "alpha risk" value to 4 decimal places.) alpha risk f. Using control limits of 0470 and 0056, is the process in control? yes O no g. Suppose that the long-term fraction defective of the process is known to be 2 percent What are the values of the mean and Standard deviation of the sampling distribution?
