Question: (a) Explain the use of the "formulas" to calculate the values of the intercept and slope of the least squares regression line on the xy-scatterplot between all 740 Glengarry houses’ pHQ2002s and their Ddowntowns.
(b) Explain the use of these intercept and slope values in the "substitution method" for predicting overall exterior housing quality percentages at three different distances from downtown. Interpret these three predicted percentages; it is optional to mark and label them on the xy-scatterplot.
