The accompanying data are the length(in centimeters) and girths(in centimeters) of 12 harbor seals. 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 givenx-values, if meaningful. If thex-value is not meaningful to predict the value ofy, explain why not.

(a) x=140 cm

(b) x=172 cm

(c) x=164 cm

(d) x=158 cm
