The accompanying data are the length in centimeters and girth’s in centimeter of 12 habor 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
