Question 1183598
1.   {{{W = 0.057*S + 0.066*E - 0.002*E^2 - 0.032*R - 0.532}}} is your multiple regression equation.


2.  This means that, every additional year of schooling increases wage by $57, and every additional year of experience increases wage by $66.  
However, any unit increase in experience-squared brings a decrease of $2, and in general Hispanics earn $32 less than non-Hispanics.


The constant coefficient provides a baseline wage for an entry level job for a new graduate, i.e., without any years of experience and initially 
graduate has no wages, and depending only on the number of years of education and Hispanicity.  This means that, non-Hispanics will have to study 
0.532/0.057  = 9.33 years to earn baseline wages, while Hispanics will have to study on average 0.564/0.057 = 9.9 years to reach same baseline wages.
