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

(a) \(x=3.5\) hours

(b) \(x=5\) hours

(c) \(x=7.5\) hours

(d) \(x=14\) 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.
