A 95% confidence interval was constructed for a population mean (sigma known). Suppose we are planning to repeat the study but we only have sufficient resources to take a sample that is one quarter the size of that used in the original study. Assuming we require the same level of confidence (and sigma has not changed), then the resulting margin of error (m.o.e.) for our new confidence interval will be:Group of answer choices √ 2 times the original margin of error 4 times the original margin of errortwice the original margin of error 1/4 times the original margin of error 1/√ 2 times the original margin of error

Compute the margin of error at a 95% confidence level. (Round final answer to 2 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 273 successes at a confidence level of 99.5%.M.E. = %

In a confidence interval, the margin of error is related to what aspect of the interval?*1 pointa. The sample sizeb. The mean of the samplec. The level of confidenced. The range of the data

What is the margin of error if the confidence level being set is 92%

A survey of a random sample of 1,500 young Americans found that 87% had earned their high school diploma. Based on these results, the 95% confidence interval for the proportion of young Americans who have earned their high school diploma is (0.853,0.887) What is the margin of error for this confidence interval? 0.95 0.87 0.034 0.017
