Find the equation ofthe regression line for the given data. Then construct a scatter plot of the data and draw the regression line. (The pair of variables have a signicant correlation.) Then use the regression equation to predict the value of y for each of the given xvalues. ii meaningful. The number of hours 6 students spent for a test and their scores on that test are shown below.
