2.8667

Step-by-step explanation:

I'm going to try and show my work on here, but it is difficult without a graph or excel spreadsheet:

Class        Grade          Credit        Points

Math            C                  5               5*2=10  

Soc              B                  3               3*3=9

Eng              B                  4               4*3=12

Music           A                 3                3*4=12                        

Total                               15               10+9+12+12=43

To get the totals I added up everything from each column.

To find the GPA, you Divide the Total Points = 43 by Total Credits = 15

43/15 = 2.8667

a. the residual plot for model 1 has a random pattern and is a good fit for the data.
