According to Reader's Digest, 43% of primary care doctors think their patients receive unnecessary medical care. a. Suppose a sample of 310 primary care doctors was taken. Show the sampling distribution of the proportion of the doctors who think their patients receive unnecessar medical care. Use z-table. E(p) (to 4 decimals) b. What is the probability that the sample proportion will be within +0.03 of the population proportion. Round your answer to four decimals. c. What is the probability that the sample proportion will be within +0.05 of the population proportion. Round your answer to four decimals. d. What would be the effect of taking a larger sample on the probabilities in parts (b) and (c)? Why? The probabilities would - Select your answer - v. This is because the increase in the sample size makes the standard error, op, Select your answer - v
