Question

value: 11.12 points Consider a population proportion p 0.31 a-1. Calculate the standard error for the sampling distribution of the sample proportion when n = 13 and n69? (Round your final answer to 4 decimal places.) Standard error 13 69 a-2 Is the sampling distribution of the sample proportion approximately normal with n = 13 and n = 69? Approximately normal (Click to select) 13 69 (Click to select)+ b. Can you use the normal approximation to calculate the probability that the sample proportion is between 0.29 and 0.31 for both sample sizes? Approximately normal 13 (Click to select) 69 (Click to select)+ c. Calculate the probability that the sample proportion is between 0.29 and 0.31 for n69. (Round "z- value" to 2 decimal places and final answer to 4 decimal places.) Probability
