5. In a large class, the instructor ran a regression with the independent variable(x) as the grade on the first exam and the dependent variable(y) being the grade on the second exam. She found the equation to be: Y = 29.25 + .57X Knowing that your friend got a 78 on the first exam, what value would you predict she got on the second exam? a) 71.43 b) 72.57 c) 78.00 d) 73.71
