Find the equation of the 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, if meaningful. The number of hours 6 students spent for a test and their scores on that test are shown below. Hours spent studying, x 1 2 2 3 4 6 E (a) x = 2 hours (b) x :45 hours Test score, y 39 43 50 49 63 72 (c) x =13 hours (d) x = 1.5 hours Find the regression equation. ;= x + ( (Round the slope to three decimal places as needed.
