The correlation coefficient is 0.56, which means that for every 1 standard deviation increase in high school GPA, we expect a 0.56 standard deviation increase in college GPA. So, for a student with a high school GPA that is 2.5 standard deviations above the mean, we would expect that student to have a college GPA that is 0.56 * 2.5 = 1.4 standard deviations above the mean.
