Module 14 covers the ordinary least squares method of a simple linear regression.  The exercises demonstrate how to calculate the least square estimates of the unknown population coefficients for a regression model with one independent variable.  Included in the exercises are calculations of the coefficient of determination and its interpretation, and hypothesis testing for the significance of individual parameters and overall model significance.  Confidence intervals are developed for both the intercept and slope coefficients.  Finally, the estimates regression equation is used for prediction.  Confidence intervals and prediction intervals are also developed for the predicted value of the dependent variable.
