Question: Using and Interpreting the Equation of a Regression Line.

Find the equation of the regression line for the given 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 given x-values, if meaningful. If the x-value is not meaningful to predict the value of y, Explain Why Not.

16 (a) x = 3 hours

16 (b) x = 9 hours
