Answer

Explanation:

Step1: Recall residual formula

Residual = Given - Predicted

Step2: Calculate residual for x = 1

Residual = $3.5 - 4.06=- 0.56$

Step3: Calculate residual for x = 2

Residual = $2.3 - 2.09 = 0.21$

Step4: Calculate residual for x = 3

Residual = $1.1 - 0.12=0.98$

Step5: Calculate residual for x = 4

Residual = $-2.2-(-1.85)=-2.2 + 1.85=-0.35$

Step6: Calculate residual for x = 5

Residual = $-4.1-(-3.82)=-4.1 + 3.82=-0.28$

Step7: Determine if line of best - fit is appropriate

A residual plot with no clear pattern indicates that the line of best - fit is appropriate.

Answer:

x Given Predicted Residual
1 3.5 4.06 -0.56
2 2.3 2.09 0.21
3 1.1 0.12 0.98
4 -2.2 -1.85 -0.35
5 -4.1 -3.82 -0.28

Yes, because the points have no clear pattern.
