Question

PLEASE ANSWER THESE TWO QUESTIONS!!

Create a residual plot for your data.

and

Using your equation from step 2d, estimate the GPA of a student who studies for 15 hours a week. Justify your answer.

Answer 1

The estimated GPA of a student who studies for 15 hours a week is 3.21.

Given:

The table with the GPA of students along with the studying hours of students.

To find:

• The residual plot for the given data.
• GPA of a student who studies for 15 hours a week.

Solution:

The residual plot of the given data is an image attached.

The equation from the plot:

$y = 0.1407x + 1.0963$

Where:

x = Hours of studies

y = GPA of student

If the student studies for 15 hours his or her GPA can be estimated as:

$y=0.1407\times 15 + 1.0963\\\\y=3.21$

The estimated GPA of a student who studies for 15 hours a week is 3.21.
