b. If the true fraction defective for this process is unknown, what is your estimate of it?

c. What is your estimate of the mean and standard deviation of the sampling distribution of fractions defective for samples of this size?

d. What control limits would give an alpha risk of .03 for this process?

e. What alpha risk would control limits of .047 and .003 provide?

f. Using control limits of .047 and .003, is the process in control?
