I just need help on questions e through. h .I just need help on questions e through. h . thank you

Using samples of 200 credit card statements, an auditor found the following: Use Table A Sample Number with errors 1 2 3 4 4 2 712 Click here for the Excel Data File a. Determine the fraction defective in each sample. (Round your answers to 4 decimal places.) Sample Fraction defective 4 it? (Round your answer to 1 decimal place.) b. If the true fraction defective for this process is unknown, what is your estimate Estimate c. What is your estimate of the mean and standard deviation of the sampling distribution of fractions defective for samples of this size? (Round your intermediate calculations and final answers to 4 decimal places.) Mean Standard deviation d. What control limits would give an alpha risk of .03 for this process? (Round your intermediate calculations to 4 decimal places. Round your "z" value to 2 decimal places and other answers to 4 decimal places.) e. What alpha risk would control limits of .0470 and .0156 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.) z= alpha risk = f. Using control limits of .0470 and .0156, is the process in control? O no O yes 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? (Round your intermediate calculations and final answers to 2 decimal places.) Mean Standard deviation h. Construct a control chart for the process, assuming a fraction defective of 2 percent, using two-sigma control limits. Is the process in control? O Yes O No
