Question

Consider a population proportion p 0.34. a-1. Calculate the standard error for the sampling distribution of the sample proportion when n 10 and n = 71 ? (Round your final answer to 4 decimal places.) Standard error 10 71 a-2. Is the sampling distribution of the sample proportion approximately normal with n 10 and n71? Approximately normal 194 10 71 (Click to select) (Click to select) b. Can you use the normal approximation to calculate the probability that the sample proportion is between 0.32 and 0.34 for both sample sizes? Approximately normal (Click to select) (Click to select 10 71 c. Calculate the probability that the sample proportion is between 0.32 and 0.34 for n 71. (Round "z- value" to 2 decimal places and final answer to 4 decimal places.) Probability
