You may also consider weighted least squares regression instead of Ordinary Least Squares regression. The errors are independent of X. This sounds like homogeneity of variance to me. Pedhazur states that these assumptions are necessary for the obtained estimators to be “best linear unbiased estimators.”

Multiple Linear Regression. Other cases including a weighted regression, more than one independent variable, cross-validated regressions, and a zero intercept require the use of the Multiple Regression module. Alas, this module does not generate a scatter plot and the full correlation matrix.

Question 1 could be addressed using either a two sample t-test or by conduction a simple linear regression Here is the R code and output for the t-test: ... 867.1 on 484 degrees of freedom Multiple R-squared: 0.005054, Adjusted R-squared: 0.002999 F-statistic: 2.459 on 1 and 484 DF, p-value: 0.1175.
