What is the margin of error for this confidence interval: (0.28, 0.32)
given the confidence interval (30% to 50%) what is margin of error?
what is the margin of error and the confidence interval? Question Help In a random sample of seven people, the mean driving distance to work was 24.7 miles and the standard deviation was 6.6 miles. Assuming the population is normally distributed and using the I-distribution, a 90% confidence interval for the population mean is (15.5, 33.9) (and the margin of error is 9.2). Through research, it has been found that the population standard deviation of driving distances to work is...
Determine the margin of error for the confidence interval for the proportion: 0.509 <u<0.845 The margin of error is
Find the margin of error for a 95% confidence interval for estimating the population mean when the sample standard deviation equals 92, with a sample size of (a) 400,(b) 1800. What is the effect of the sample size? 2. The margin of error for a 95% confidence interval with a sample size of 400 is (Round to the nearest tenth as needed.) b. The margin of error for a 90% confidence interval with a sample size of 1600 is (Round...

Determine the margin of error for a confidence interval to estimate the population mean with nequals22 and s = 11.6 for the confidence levels below. a) 80% b) 90% c) 99% a) The margin of error for an 80% confidence interval is nothing.
Question 4 0/20 pts What is the relationship between the width of the confidence interval and the margin of error? © They are unrelated concepts. They are identical. The margin of error is twice the length of the confidence interval. The length of the confidence interval is twice the margin of error.
6.12 Margin of error and the confidence interval. A study of stress on the campus of your university reported a mean stress level of 78 (on a 0 to 100 scale with a higher score indicating more stress) with a margin of error of 5 for 95% confidence. The study was based on a random sample of 64 undergraduates more e. The study w (a) Give the 95% confidence interval. (b) If you wanted 99% confidence for the same study,...
