ssume that population proportion is to be estimated from the sample described. Use the sample results to pproximate the margin of error and 95% confidence interval. Sample size, n = 580; sample proportion, p=0.7 he margin of error is 0.0373. Round to four decimal places as needed.) ind the 95% confidence interval.

Construct a confidence interval for p, - p, at the given level of confidence. X1 = 381, n1 = 507, x2 = 424, n2 = 563, 95% confidence %3D The researchers are % confident the difference between the two population proportions, p, - P2, is between and (Use ascending order. Type an integer or decimal rounded to three decimal places as needed.)

Use the confidence interval to find the margin of error and the sample mean. (1.62,2.00) The margin of error is (Round to two decimal places as needed.)

Use the given confidence interval to find the margin of error and the sample mean. (15.3,23.7) The sample mean is . (Type an integer or a decimal.) The margin of error is. (Type an integer or a decimal.)
