Data comprises of the number of hours studied (X) and the exam grade (Y) obtained for 6 first year students registered at UWC. The equation of best fit is given by: y = 67.071 + 4.535x. The correlation coefficient is found to be 0.557, which implies that the coefficient of determination is …………, and that …………….. A. 0.557, about 55,7% of the variation in Y is explained by the estimated line of best fit. B. 55.7%, the time (in hours) spent studying has a positively correlation with the grade obtained in the exam. C. 0.7463, about 74.6% of the variation in Y is explained by the estimated line of best fit. D. 0.310, about 31% of the variation in Y is explained by the estimated line of best fit.
