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 1 3 3 4 5 (a) x = 2 hours (b) x =4.5 hours Test score, y 39 43 50 47 63 69 (c) x= 13 hours (d) x = 3.5 hours Find the regression equation. y =[x + 0 (Round the slope to three decimal places as needed Round the y-intercept to two decimal places as needed.)
