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. font size decreased by 1 font size increased by 1 hours spent studying comma xhours spent studying, x 00 22 22 44 55 66 (a) xequals=33 hours (b) xequals=4.54.5 hours test score, y 4040 4545 4949 4747 6262 7070 (c) xequals=1515 hours (d) xequals=2.52.5 hours
