Question 7 of 24 - 11 8 ... View Policies Current Attempt in Progress 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 95% confidence interval for p given that p = 0.8 and n = 140. Round your answer for the point estimate to two decimal places, and your answers for the margin of error and the confidence interval to three decimal places. Point estimate = Margin of error = + i The 95% confidence interval is to eTextbook and Media
