Build a model to predict life expectancy by state using the state statistics we have in our dataset (statedata.csv).
 The model with all potential variables included
(Population, Income, Illiteracy, Murder, HS.Grad, Frost,
and Area).
 Note that you should use the variable "Area" in your
model, NOT the variable "state.area".
 Question: What is the coefficient for "Income" in your
linear rregression model?
