Question

practice computing and analyzing residuals. the predicted values were computed by using the line of best fit, y = 3.2x + 2. what are the residual values needed to complete the chart?

x	given	predicted	residual
2	7.4	8.4	b
3	11	11.6	c
4	15	14.8	d

Explanation:

Step1: Recall residual formula

Residual = Given - Predicted

Step2: Calculate value of a

a = 6.1 - 5.2 = 0.9

Step3: Calculate value of b

b = 7.4 - 8.4=-1

Step4: Calculate value of c

c = 11 - 11.6=-0.6

Step5: Calculate value of d

d = 15 - 14.8 = 0.2

Answer:

a = 0.9
b = -1
c = -0.6
d = 0.2
