The number of hours 9 students spent studying for a test and their scores on that test

(a) x = 3 hours

(b) x = 6.5 hours

(c) x = 13 hours

(d) x = 4.5 hours

Find the equation of the regression line for the 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 x-values, if meaningful. If the x-value is not meaningful to predict the value of y, explain why not. If convenient, use technology.
