Using technology, it was determined that the total sum ofsquares (SST) was 4029.2, the sum ofsquares regression (SSR) was 3968.4, andthe sum of squares due to error (SSE)was 60.835. Calculate R2 and determine its meaning. Roundyour answer to four decimal places.
Select the correct answer below:
R2=0.0153
Therefore, 1.53% of the variation in the observedy-values can be explained by the estimated regressionequation.
R2=0.9849
Therefore, 98.49% of the variation in the observedy-values can be explained by the estimated regressionequation.
R2=0.0151
Therefore, 1.51% of the variation in the observedy-values can be explained by the estimated regressionequation.
R2=1.0153
Therefore, 10.153% of the variation in the observedy-values can be explained by the estimated regressionequation.
