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 336 with 35.1% successes at a confidence level of 99.5%. M.E. = % Report answer accurate to one decimal place (as a number of percentage points). 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 259 with 74.9% successes at a confidence level of 99%. M.E. = % Report answer accurate to one decimal place (as a number of percentage points). 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 359 with 201 successes at a confidence level of 99.9%. M.E. = % (report answer accurate to one decimal place; answer should be reported as a percent, not a decimal—though do not type the percent sign) 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 μμ. Find the margin of error M.E. that corresponds to a sample of size 748 with a mean of 49.5 and a standard deviation of 5.5 at a confidence level of 99.5%. Report ME accurate to one decimal place because the sample statistics are presented with this accuracy. M.E. = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
1. Express the confidence interval 86.5%±4.6% in interval form 2. 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 217 with 23% successes at a confidence level of 80%. M.E. = % 3.A political candidate has asked you to conduct a poll to determine what percentage of people support her. If the candidate only wants a 6% margin of error at a 99% confidence...
Assume that a sample is used to estimate a population proportion μμ. Find the margin of error M.E. that corresponds to a sample of size 37 with a mean of 54.8 and a standard deviation of 9.6 at a confidence level of 99%. Report ME accurate to one decimal place because the sample statistics are presented with this accuracy. M.E. = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
