A guidance counselor at a local high school is interested in determining what, if any, linear relationship there is between high school percentile ranks and college GPAS. A student's percentile rank is calculated by determining the percentage of all students in the graduating class with a final high school GPA at or below his or hers. For example, a student graduating 10th in a class of 300 would have a percentile rank (to one decimal place) of (290/300)x100 - 96.7....
