Exercise 7.35 algorithmic Thirty five percent of all americans drink bottled water mpre than once a week(national resources defense council, december 4, 2015). Suppose you have been hired by the natueal resoyrces defence council to investigate bottles water consumption in st. Paul. You plan to select a samole of St. Paulites to eatimate the proporrion who drink bottled wayee more than once a wwek. Assume the popluation proportion of St Paulituesvwho drink bottle water more than once a week is 0.35, the same as the overall proportion of americans who drink bottled wayer more than once a week. Need help with A. Suppose you select a sample of 530 st.Paulites. show the sampling of p to 4 decimals. Op = ? B.based upon a sample of 540 St. Paulites, what is the probability that the sample proportuon will be within 0.03 of the pipulation proportion to the 4 decimal. Probability? C. Suppose you select a sample of 199 st. Paulites. Show the sampling distribution of p to 4 decimals. E(p)= ? Op=? D. Based upon a smaller samply of only 190 St. Paulites, what ia the probabikitt that the sample proportion will be within 0.03 of the pipulation propoetio to the 4 decimal. Probability ? E. As measured by the increase in probabilty , how much do yiu gain in prevision by taking the larger samole in parts a and b rathee than the samllee in parts c and d. Reduced by correct. ?
