exercise 50 53 56 60 64 35 44 49 65 69 Using technology it was determined that the total sum of squares SST was 819 2 the sum of squares regression SSR was 794 19 and the sum of squares due to error SSE was 25 013 Calculate R and determine its meaning Round your answer to four decimal places Select the correct answer below R 0 0305 Therefore 3 05 of the variation in the observed y values can be explained by the estimated regression equation R 1 0315 Therefore 10 315 of the variation in the observed y values can be explained by the estimated regression equation R 0 0315 Therefore 3 15 of the variation in the observed y values can be explained by the estimated regression equation R 0 9695 O Therefore 96 95 of the variation in the observed y values can be explained by the estimated regression equation E
