Assume that a sample is used to estimate a population proportion p. Find the margin of error M.E. that corresponds to a sample of size 81 with 28.4% successes at a confidence level of 99.5%. M.E. = % Round to 4 places. Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.

Assume that a sample is used to estimate a population proportion p. Find the margin of error M.E. that corresponds to a sample of size 311 with 280 successes at a confidence level of 98%. M.E. = % Round to 1 decimal place.

If n = 420 and p (p-hat) =0.75, find the margin of error at a 99% confidence level. . Round to 4 places. Z-scores may be rounded to 3 places or exact using technology.

Express the confidence interval 31.8 % £ 5.4 % in interval form. Enter in interval notation. Do not enter as a percent.
