A student is interested in which factors affect the U.S. poverty rate and develops a model using the following independent variables:
The unemployment rate The percent of the adult (over 25) population with at least a bachelor's degree The percent of the population without health insurance
The student collects data from each of the 50 states in the U.S. and Washington D.C. for the year 2012 and runs the regression in Excel. The results of this regression are given below. Based on these results, what does the model predict the poverty rate would be for a state for which the unemployment rate is 6%, 20% of all adults over 25 have at least a bachelor's degree, and 5% of the population does not have health insurance?
(Note that all percent values are given as numbers between 0 and 1.)
