Question
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 given x-values, if meaningful. If the x-value is not meaningful to predict the value of y, explain why not.
