One recent study found that online math and statistics training quizzes worked quite well. The regression equation, Q = 91.771 3.67911, expresses statistical dependence of the final grade in statistics (3}) on the number of quizzes missed by students (at) in a sample of 14 statistics students. If the coefficient of determination is r2 = 0.8588, then the coefficient of correlation is O 0.738 O 7 0.927 O 0.927 O 7 0.966 O 0.938 O 7 0.902 O 0.8588 0 7 0.972 0 None of the above
