Unit 2 Quiz Review

1) Suppose the least squares regression line for a two-variable dataset is 

predictedY = -2x +19

What is the predicted y value when x = 3?

Initialize the value of 'predictedY' below.

2) Suppose the least squares regression line for a two-variable dataset is 

predictedY = 3x +25

One of the points in the dataset is (5, 38).  What is the residual for this point?

Initialize the value of 'residual' below.

3) Using the graph above, what is the predicted Y value for the point (4, 2)?  Initialize the value for 'predictedY' below.

4) What is the residual value for the point (4, 2)?  Initialize the value for 'residual' below.
