Suppose you have been hired by the Natural Resources Defence Council to investigate bottled water consumption in St. Paul. You plan to select a sample of St. Paulites to estimate the proportion who drink bottled water more than once a week. Assume the popluation proportion of St. Paulites who drink bottled water more than once a week is 0.33, the same as the overall proportion An ericans who drink bottled more than once a week. Use z-table. a. Suppose you select a sample of 540 St. Paulites. Show the sampling distribution of p (to 4 decimals). E(F): 0.33 0.0202 b.
