Describe the unexplained variation about a regression line in words and in symbols. y X (xi, Yj) • (,,)) (x, y) y = y Choose the correct answer below. O A. The unexplained variation is the sum of the squares of the differences between the y-values of each ordered pair and the mean of the y-values of the ordered pairs. B. The unexplained variation is the sum of the squares of the differences between the observed y-values and the predicted y-values. OC. The unexplained variation is the sum of the squares of the differences between the predicted y-values and the mean of the y-values of the ordered pairs.

(Round to three decimal places as needed.) How can the coefficient of determination be interpreted? O A. The coefficient of determination is the fraction of the variation in sales that is unexplained and is due to other factors or sampling error. The remaining fraction of the variation explained by the variation in total square footage. O B. The coefficient of determination is the fraction of the variation in sales that can be explained by the variation in total square footage. The remaining fraction of the variation is unexplained and is due to…
