X1 is a time variable that is coded 1 for 1985 and increases by one for each year. X2 is the unemployment rate in Wisconsin. A regression produces the following result:

R2 = .99 sb = 9.1 11.5 Sy|x = 32.4
Interpret this regression. Are the relationships significant? If the unemployment rate for 2015 is projected to be 6.2%, what is your best guess as the income tax revenue.
