(Round calculated results to the hundredth (2nd place to the right of the decimal) when result extends
beyond that unless otherwise noted).
It is generally believed that there is a relationship between a college's acceptance rate and its
graduation rate. I wanted to know how strong this relationship is within the top universities in the
country, so I collected the graduation rate and acceptance rate data of a randomly selected sample of
universities from all the top U.S. universities (with an acceptance rate at or below 30%). The data set is
in Tab Q2 of the Excel data file.
Ola Create a scatter plot between the two variables using Excel. Paste the plot here and format it into
