Thirty five percent of all americans drink bottled water more than once a week. Suppose you have been hired by the naturL resources defence council to investigate bottled water consumptuon in st paul. You plan to select a sample of St. Paulities to estimate the proportion whobdrink bottled water more than once a week. Assume the popluation proportion of st. Paulites whobdrink bottled water than once a week is .35 the same as the overall proportion of americans who drink botttles water more than once a week. D. Based upon a smaller samplebof only 190 st. Paulities what ia the probability that the sample peopoetion wikk be within 0.03 of the population proportion to the 4th decimal probability = ? E. As measured by the increase in probability how much do yiu gain in precision by taking the larger sample in parts a and b rather than the smaller sample in parts c and d Thank you for your help
