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.

Use the normal distribution to nd a condence interval for a proportion :1 given the relevant sample results. Give the best point estimate for p. the margin of error, and the condence interval. Assume the results come from a random sample. A 90% condence interval for in given that i! = 0.4 and n = SUG- Round 1your answer for the best point estimate to two decimal places, and your answers for the margin of error and the condence interval to three decimal places
