The slope of the least-squares regression line is always between −1 and 1. The least-squares regression line always goes through the point ( ̅ x , ̅ y ). The least-squares regression line minimizes the sum of squared residuals.

(a) Draw the least squares regression line on the scatterplot below. (b) One father’s height was x = 67 inches and his daughter’s height was y = 61 inches. Circle the point on the scatterplot above that represents this pair and draw the segment on the scatterplot that corresponds to the residual for it.

This is usually done by fitting a line to the observations in the sample and using the fitted line’s intercept, b0, and slope, b1, as the parameter estimates. Ordinary Least Squares (OLS or LS) fits the line by finding the intercept and slope that minimize the sum of squared residuals (SSR) is found.

When the observed responses fall close to the regression line, SSE will be small. When the data are not near the line, SSE will be large. Finally, there is a third quantity, representing the deviations of the predicted values from the mean. Then these deviations are squared and summed up, this is referred to as the regression sum of squares (SSR).

(b) The equation of the least-squares regression line is = 4.535 + 0.030x, where = predicted tip amount (in dollars) and x = length of stay (in minutes). (c) Slope: For each additional minute that a party stays at the buffet, the least-squares regression line predicts an increase in the tip of $0.030 (3 cents).

A least-squares regression line for predicting performance on a college entrance exam based on high school grade point average (GPA) is determined to be Score = 273.5 + 91.2(GPA). One student in the study had a high school GPA of 3.0 and an exam score of 510. What is the residual for this student?
