The accompanying data are the shoe sizes and heights (in inches) of

14

men. 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.

(a) x=11.5

(b) x=8.0

(c) x=15.5

(d) x=10.0
