Flavia wanted to estimate the mean age of the faculty members at her large university. She took an SRS (simple random sample) of 202020 of the approximately 700700700 faculty members, and each faculty member in the sample provided Flavia with their age. The ages were skewed to the right with a sample mean of \bar x =38.75
x
ˉ
=38.75x, with, \bar, on top, equals, 38, point, 75. She's considering using her data to make a confidence interval to estimate the mean age of faculty members at her university.
