Robin wanted to know if the age partition chosen for her data was the best fit for her 40 case, 90% Class 1, 10% Class 0 partition. She completed the Gini impurity index with the results of (Age < 32) = 0.2284 and (Age >= 32) = 0.2999. What is the weighted combination and what did partition at Age 32 produce? Multiple Choice Robin was able to reduce the Gini index from 0.2999 to 0.2699 confirming the best split for age. Robin was able to reduce the Gini index from 0.2999 to 0.20 confirming the best split for age. Robin was able to reduce the Gini index from 0.2999 to 0.2356 confirming the best split for age. Robin realized with the 0.2699 weighted average, the age split was not the best split for the age range.
