Answer:
e=20
Step-by-step explanation:
Given there is a scatter plot.
A point on it is (10,7)
The regression line y' = -x-3
We have regression line giving estimate for given value of x
When x=10, actual value of y
= y observed = 7 (given)
As per regression line estimate
y = -10-x = -13
Difference between y estimate and actual y = 7-(-13)
=20
