Thirty-five percent of all Americans drink bottled water more than once a week (Natural resources Defense Council, December 4, 2015). 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 0.35, the same as the overall proportion of Americans who drink bottled water more than once a week. 1. Based upon a smaller sample of only 290 St. Paulites, what is the probability that the sample proportion will be within 0.01 of the population proportion (to 4 decimals).
