Question

The scatter plot shows the time spent studying, x, and the midterm score, y, for each of 24 students.Matem score

Answer 1

We have the next equation

`y=3.78x+15.88`

For a.

x=0

`y=3.78(0)+15.88`
`y=15.88`

The predicted midterm score for a student who doesn't spend any time studying is 15.88

for b.

x=18

`y=3.78(18)+15.88`

The predicted midterm score for a student who studies for 18 hours is 83.92

for c.

For an increase of one hour in the time spent studying What is the predicted increase in the midterm score? it i the value of the slope in the equation given it is 3.78
