Suppose we found the following regression equation for weight vs. height. weight =−222.5+5.49 height Interpret the slope of the regression equation. Does the intercept have a meaningful interpretation? If so, interpret the value.

The accompanying data are the caloric contents and the sugar contents​ (in grams) of 11 ​high-fiber breakfast cereals. Find the equation of the regression line. Then construct a scatter plot of the data and draw the regression line. Then use the regression equation to predict the value of y for each of the given​ x-values, if meaningful. If the x-value is not meaningful to predict the value of​ y, explain why not.  Calories, x         Sugar, y 140                      6 200                     10 160                      6 160                      9 170                     10 180                     16 190                     13 210                     18 190                     19 170                     10 170                     10   The equation of the regression line is ŷ =  ______ x + ______ ​(Round the slope to three decimal places as needed.

The accompanying data are the number of wins and the earned run averages (mean number of earned runs allowed per nine innings pitched) for eight baseball pitchers in a recent season. Find the equation of the regression line. Then construct a scatter plot of the data and draw the regression line. Then use the regression equation to predict the value of y for each of the given x-values, if meaningful. If the x-value is not meaningful to predict the value of y, explain why not.
