A Sampling Distribution for Two-Year College Enrollments The dataset CollegeScores2yr gives enrollments for all 1141 two-year colleges in the US in 2019. Use StatKey or other technology to generate a sampling distribution of sample means using a sample size of n = 10 from the Enrollment values in this dataset.
(a) What shape does the distribution have? Approximately where is it centered? What is the standard error (in other words, what is the standard deviation of the sample means)?
(b) What happens if we increase the size of each sample to n = 60? What shape does the distribution have? Approximately where is it centered? What is the standard error (in other words, what is the standard deviation of the sample means)?
