I wish to estimate the proportion of defectives in a large production lot with plus or minus D = 0.02 of the true proportion, with a 95% level of confidence. From past experience it is believed that the true proportion of defectives is π = 0.02. How large a sample must be used? (Hint: Use a normal approximation for the sample proportion P
