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 90% confidence interval for p given that p = 0.8 and n = 120. 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= i Margin of error = + The 90% confidence interval is to eTextbook and Media Save for Later Attempts: 0 of 3 used Submit
