Question

In this scatterplot the individuals are states. The variable "cig" is the number of cigarettes sold per person in the state in 1960. The variable "lung" is the deaths from lung cancer per 100,000 people in the state in 1990. For the state of Wyoming (WY), Cig =28.04, the observed lung value is 15.92, and the predicted lung value is 21.33. Compute the residual for this point.

Answer 1

e= -5.41

Explanation:

Hello!

In linear regression, a residual value is a distance between the observed values and the regression line.

The residual value (e) is calculated as the difference between the observed value (Y) and the predicted value (^Y).

e= Y - ^Y

e= 15.92 - 21.33 = -5.41

I hope it helps!
