Because there is no indication of which node represents an ancestor, there is no direction of an evolutionary path in an unrooted tree.

Because there is no indication of which node represents an ancestor, there is no direction of an evolutionary path in an unrooted tree. Correct Answer True

To define the direction of an evolution path, a tree must be rooted. In a rooted tree, all the sequences under study have a common ancestor or root node from which a unique evolutionary path leads to all other nodes.

Having built a decision tree, we are using reduced error pruning to reduce the size of the tree. We select a node to collapse. For this particular node, on the left branch, there are 3 training data points with the following outputs: 5, 7, 9.6 and for the right branch, there are four training data points with the following outputs: 8.7, 9.8, 10.5, 11. What were the original responses for data points along the two branches (left & right respectively) and what is the new response after collapsing the node?
