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?\n|x|given|predicted|residual|\n|----|----|----|----|\n|1|6.1|5.2|a|\n|2|7.4|8.4|b|\n|3|11|11.6|c|\n|4|15|14.8|d|
Answer
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
