4. The regression line for this bivariate data set is = 19.41 + .17x. What is the residual for the point with an x-value of 68? x 56 45 68 49 58 63 66 62 y 28 25 34 30 32 36 23 29
1 answer:
Answer:
3.03
Step-by-step explanation:
x y
56 28
45 25
68 34
49 30
58 32
63 36
66 23
62 29
slope 0.174993175
Intercept 19.40977341
is the regression line
As per line, we can find y for x=68 as
For x=68
y actual = 34
y predicted = 30.97
Residual = 34-30.97
= 3.03
