Question

A scatter plot containing the point (10, 7) has the regression equation yˆ=−x−3 .

What is the residual e when x = 10?



Enter your answer in the box.

e=__

Answer 1

20 is the answer ihope this helllllllllllps

Answer 2

e=20

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
