A scientific study on speed limits gives the following datatable.

Average speed limitAverage annualfatalities
2516
2729
2938
3271
3593

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.
