A large retailer wants to estimate the proportion of Hispanic customers in a particular state. First, think about how large a sample size (of the retailer’s customers) would be needed to estimate this proportion to within 0.04 accuracy and with 99% confidence. Assume there is no planning value for p* available. Which of the following statements would be true IF you decided to go for 0.01 accuracy instead of 0.04 accuracy?   a. Sample_size for (0.01) = 16*Sample_size for (0.04)   b. Sample_size for (0.01) = 4*Sample_size for (0.04)   c. Sample_size for (0.01) = (1/16)*Sample_size for (0.04)   d. Sample_size for (0.01) = Sample_size for (0.04) as long as the confidence level is the same.
