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? 0.87 0.017 0.95 0.034

A random sample of 30 students taking statistics at a community college found the student’s mean GPA to be 3.25. A 95% confidence interval for the mean GPA of all students taking statistics at this college was determined to be (3.07, 3.43). What is the margin of error for this confidence interval? 0.18 0.95 3.25 0.36

Researchers surveyed 1,150 high school students in CA to estimate the proportion of all high school students who vape. 368 of the surveyed students said they do vape. What is the margin of error of the 95% confidence interval?

Compute the margin of error at a 95% confidence level. (Round final answer to 2 decimal places.)

A survey was given to a random sample of the residents of a town to determine whether they support a new plan to raise taxes in order to increase education spending. The survey reported a confidence interval that between 43.5% and 48.5% of the residents supports the plan. What is the margin of error on the survey?

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. = %
