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:

Y = 1.2 + 0.005(W)

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

Y(159) = 1.2 + 0.005(159) = 1.995

b) 300

Y(300) = 1.2 + 0.005(300) = 2.7

c) 500

Y(500) = 1.2 + 0.005(500) = 3.7

d) 550

Y(550) = 1.2 + 0.005(550) = 3.95

True or False?:
Marizza181 [45]

The first statement is true, because the two negative signs cancel each other out. However, the second is false because any time you multiply a positive number by a negative number the product is always negative. Therefore 4x-6=-24
