(8) Sampling distribution for a population's proportion According to a national research center, 72% of Americans are satisfied with the way things are going in their lives. Therefore, the population proportion p = .720 (a) Suppose random sample size is n = 300. Then the p sampling distribution can be described by Shape: Normal/bell-shaped Center: mean = .720 Spread: std.dev. = ? (b) Draw the normal curve for this p sampling distribution. Make sure to label the tick marks for center and inflection points. (c) In a random sample of three hundred Americans, find the Probability that the proportion of satisfied Americans is greater than .730 Make sure to shade and label the probability region under your normal curve, and show normalcdf with the exact std.dev. Round your final answer to four decimal places
