This continues to use the Problem I water quality data you downloaded. What is the sampling standard deviation for the ranks?  In other words, what is σW?

Below is a screenshot of a multiple linear regression you colleague has run.  She is trying to predict the sale price of real estate, given a few factors: * the Lot Size, given in square units * Whether or not the house is in the water district or not (if not, they need their own well water) * How many minutes it is to drive downtown during rush hour * The schools rating (higher is better) She has run the following multiple linear regression output in Excel.  Write a brief essay evaluating how good this regression model is.  Use a 95% level of statistical significance (so alpha = 0.05.)  Make sure you address issues of statistical significance, outliers, and anything else.  You should answer the question:  is this model pretty good as it is, or if changes need to be made, what and why?
