The regression equation, y ˆ = 93.11 - 7.196x, expresses statistical dependence of the final grade in statistics (y) on the number of classes missed by students (x) in a sample of 75 statistics students. If the coefficient of determination is r^2 = 0.5921, how much of the variation of the final grades in statistics can be explained by the variation of the numbers of classes missed by students?

Answer #1

we ahve goven the value of coefficient of determination R2 = 0.5921

about 59.21% variation of the final grades in statistics can be explained by the variation of the numbers of classes missed by students
