According to a recent Gallup Poll, 21% of Americans believe that healthcare is the most important problem in America. Let p be the proportion of people who believe that healthcare is the most important problem in America out of a random sample of 660 Americans. Determine the following probabilities. Round probability solutions to four decimal places and p values to two decimal places, if necessary. Find the probability that in a random sample of 660 Americans, at most 139 people believe that healthcare is the most important problem in America. P(p < 9 Find the probability that in a random sample of 660 Americans, between 132 and 158 people believe that healthcare is the most important problem in America. PO x <p < Hint: First calculate the sample proportions, p, for each probability exercise. The value of p is calculated by taking the number of observations in the sample with the given characteristic and dividing by the sample size.
