find the residual values, and use the graphing calculator tool to make a residual plot.\ndoes the residual plot show that the line of best fit is appropriate for the data?\nyes, because the points have no clear pattern.\nno, the points have no pattern.\nno, the points are in a linear pattern.\nyes, the points are in a curved pattern.\n|x|given|predicted|residual|\n|----|----|----|----|\n|1|3.5|4.06|\n|2|2.3|2.09|\n|3|1.1|0.12|\n|4|-2.2|-1.85|\n|5|-4.1|-3.82|
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.
