Use the normal distribution to find a confidence interval for a proportion p given the relevant sample results. Give the best point estimate for p, the margin of error, and the confidence interval. Assume the results come from a random sample. A 90% confidence interval for p given that p = 0.43 and n = 475. Round your answer for the best point estimate to two decimal places, and your answers for the margin of error and the confidence interval to three decimal places. Best point estimate = 0.43 Margin of error = ± 0.037 The 90% confidence interval is i to i !
