From a random sample ofn= 6 college students, a school counselor obtained the students high school ...

From a random sample ofn = 6 college students, a school counselor obtained the students’ high school GPAs (x) and their college GPAs (y). Using these data, she wishes to develop a model that will allow her to predict a student’s college GPA from his or her high school GPA.

Student number	1	2	3	4	5	6
HS GPA (x)	2.78	3.82	3.16	3.53	2.96	3.37
College GPA (y)	2.95	3.64	3.55	3.89	3.06	3.31

What is the fitted least-squares regression equation?

▸

y= 0.326 + 0.8660x

▸

y= 3.360 + 0.0114x

▸

y= 0.887 + 0.769x

▸

y= 76.985 – 248.344x
