Explanation / Answer
Given that At a hypothetical university, theplot of first and second year GPA's is football shaped, and thecorrelation is 0.5(r) i.e., the percentage of variation isr2 = (0.5)2 =0.25 Without the values of means and SDs of theGPA's we cannot find out the percentile would you predict for thesecond year GPA of a student who had a first year GPA at the 89thpercentile
