Let TT represent the population proportion of adult Americans who respond favorably when asked about the president's job performance. Suppose that 50% of adult Americans respond favorably when asked about the president's job performance, and suppose you plan to take a simple random sample (SRS) of n adult Americans. a. Use the Central Limit Theorem to calculate the standard deviation of the sampling distribution of the sample proportion of adult Americans who respond favorably, for each of the following values of n. Round your answers to four decimal places. When n = 300, standard deviation =
