Question: A journal article reported that for the 1998 - 1999 academic year, four-year private colleges charged students an average of $9362 for tuition and fees. Suppose that for 1999 - 2000, a random sample of 39 private colleges yielded the following data on tuition and fees:

\(\bar{X}\) = $9952 and s = $2559

Assume that $9362 is the population mean for 1998 - 1999. Calculate the test statistic to test that the mean for 1999 - 2000 is greater than the mean for 1998 - 1999.
