Question

A data set has the following equation for the regression line (that is, line of best fit): y = 22x - 10. Determine the residual of the data point (5.2, 100.5).

Answer 1

Solution:

We are given that equation for the regression line:

y =22x - 10

We have to determine residual for the data point (5.2 , 100.5)

Residual is given by formula

Where yi is actual y value=100.5

And

Thus residual is
