The following table gives the Hay Point (HP) total for five female jobs and the corresponding monthly salary (S).

A least squares regression applied to data for the male occupations yielded the following relationship: S_i = 1200 + 0.90 HPi.
Using the “male” equation, estimate the earnings that the females would have earned based on the HP level of the occupation.
Analyze whether discrimination appears to exist. Is there a pattern by skill level?
