Average Math SAT score=540Average first-year GPA=2.6r=0.58SD=100SD=0.8 The scatterplot of their first-year GPAs on Math SAT scores is an oval-shaped cloud of points.

Suppose a student from this freshman class at Galton University takes the SAT again during the summer and gets a score 75 points higher than his original score. By how much will his first-year GPA increase?

058*(0.8/100)*75= 0.348 is wrong!
