You begin by collecting data about students at two local colleges: Private University X and State University Y. You want to find out how many students at each university have "high" (or "heavy") levels of student loan debt, which you define as $25,000 or more. You get the following raw numbers about students at Private University X: 8,500 students graduated in 2017; 5,500 students had $25,000 or more in student loans, and 2,500 students had less than $25,000. You get the following raw numbers about students at State University Y: 9,000 students graduated in 2017; 2,500 students had $25,000 or more in student loans, and 6,500 students had less than $25,000. You want to compare the amount of students with high levels of student loan debt at Private University X with State University Y. Which type of descriptive statistics should you use to accomplish this
