Choose thy correct graph below.
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 Test score, y (a) x=3 hours (c) x= 13 hours (b) x= 2.5 hours (d) x= 3.5 hours 4 40 45 52 47 63 72 Find the regression equation. y= 4.689 x+ (38.32) (Round the slope to three decimal places as needed. Round the y-intercept to two decimal places as needed.) Choose thy correct graph below OA. O B Oc. OD. Hours studying Hours studying Hours studying Hours studving
