Regression Equation

Using spss to estimate the regression equation. I am interested in knowing what factors/variables explain the variation in student iq. I believe that student age, height and income have a statistically significant influence on student iq. Estimate the regression equation, explain what the adjusted r square represents, and which variables are statistically significant and which ones are not. Test at the .05 level of significance.

Due by April 20.

Make sure you define the dependent and independent variables correctly
