Answer: (5, 2.7) residual plot is correct .
Step-by-step explanation:
Given : model the data is y = –0.33x + 4.27.
To find :Which residual plot is correct (1, 4.0), (2, 3.3), (3, 3.8), (4, 2.6), (5, 2.7).
Solution : We have given that :
y = –0.33x + 4.27.
Substitute x=1 , y = –0.33(1) + 4.27 = 3.94 incorrect
Substitute x=2 , y = –0.33(2) + 4.27 = 3.61 incorrect
Substitute x=3 , y = –0.33(3) + 4.27 = 3.28 incorrect
Substitute x=4 , y = –0.33(4) + 4.27 = 2.95 incorrect
Substitute x=5 , y = –0.33(5) + 4.27 = 2.62 correct
Therefore , (5, 2.7) residual plot is correct .
