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 significant correlation.) Then use the regression equation to predict the value of y for each of the given x-values, 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 0 2 4 5 5 (a) x = 2 hours (b) x = 2.5 hours Test score, y 38 43 51 49 63 72 (c) x = 12 hours (d) x = 3.5 hours Find the regression equation. y =x +(D (Round the slope to three decimal places as needed. Round the y-intercept to two decimal places as needed.)
