Determine the z-scores of the largest and smallest values in each column. The report should include the two columns of data, a scatter plot of the data along with the regression line. State the regression coefficient, and what the coefficient of determination says about the correlation. Comment about the level of significance of the correlation. (Look at the P-value of the slope.) Interpret the slope of the line in the context of the data, and of the y-intercept, if it makes sense to do so, or state why it doesn't. Demonstrate that the point ( - x , - y ) satisfies the linear equation. Finally, determine the largest residual value.
