I worked through the 14 problems on the 2nd part of the exam using a calculator and pencil + paper. I’ve scanned in my hand written solutions.
First, calculate ∑x, ∑y, ∑x², ∑y², ∑xy and produce a scatter plot.
Next, calculate the Pearson Correlation Coefficient, identify correlation type, dependent and independent variables, calculate slope and y-intercept of the regression line and produce a linear equation.
Finally, calculate the Sum of Squares Error (SSE), Standard Error of the Estimate, Coefficient of Determination (r²), estimate property values and discuss how multiple regression might be utilized.
Here is the formula sheet that was provided, for reference.
