fertilizer distance 15 88 15 101 18 116 20 21 93 122 Using technology, it was determined that the total sum of squares (SST) was 854, the sum of squares regression (SSR) was 257.18, and the sum of squares due to error (SSE) was 596.82. Calculate R2 and determine its meaning. Round your answer to four decimal places. Select the correct answer below: R2 0.6989 Therefore, 69.89% of the variation in the observed y-values can be explained by the estimated regression equation. R2 0.3011 Therefore, 30.11% of the variation in the observed y-values can be explained by the estimated regression equation. R2 3.3200 Therefore, 3.32% of the variation in observed y-values can be explained by the estimated regression equation. R2 2.3200 Therefore, 2.32% of the variation in the observed y-values can be explained by the estimated regression equation.
