The National Assessment of Educational Progress (NAEP) includes a mathematics test for high school seniors. Scores on the test ranges from 0 to 300. Suppose the standard deviation of the NAEP math score for 12th graders nationally is 35.
If you take a SRS of 50 12th-graders, and find out their average grade is 145, what is the 95% confidence interval of the average NAEP math score? If you take a SRS of 100 12th-graders, and find out their average grade is 145, what is the 95% confidence interval of the average NAEP math score?
