The caloric contents and the sodium contents (in milligrams) of 10 beef hot dogs

(a) x = 170 calories

(b) x = 100 calories

(c) x = 140 calories

(d) x = 210 calories

Find the equation of the regression line for the data. Then construct a scatter plot of the data and draw the regression line. (Each pair of variables has a significant correlation.) Then use the regression equation to predict the value of y for each of the x-values, if meaningful. If the x-value is not meaningful to predict the value of y, explain why not. If convenient, use technology.
