Answer:
a) 1.995
b) 2.7
c) 3.7
d) 3.95
Step-by-step explanation:
We are given the following information in the question:
[tex]Y = 1.2 + 0.005(W)[/tex]
is the regression line for the relationship between W and Y, where W represents aptitude test scores and Y represents grade point average in college.
We have to predict GPA for people who scored each of the following scores on the aptitude test:
a) 159
[tex]Y(159) = 1.2 + 0.005(159) = 1.995[/tex]
b) 300
[tex]Y(300) = 1.2 + 0.005(300) = 2.7[/tex]
c) 500
[tex]Y(500) = 1.2 + 0.005(500) = 3.7[/tex]
d) 550
[tex]Y(550) = 1.2 + 0.005(550) = 3.95[/tex]
