To the expert who answered the same question before but couldn't since I didn't include the data (https://www.chegg.com/homework-help/questions-and-answers/2-following-dataset-4-black-dots-5-white-dots-data-points-integer-aligned-coordinate-value-q108904188), I'm sorry I was so dumb; here you go. You are a legend :)

(If you aren't the person who answered before, also feel free to answer, I'll upvote as long as it's a correct and step-by-step answer)

2. For the following dataset with 4 black dots and 5 white dots (data points), with integer aligned coordinate values, construct a decision tree to attain 100% accuracy on the 9 points. a) Draw the tree and label all the nodes appropriately. Note that you are NOT required to show the steps. b) Draw the corresponding decision boundary of the tree you provided in part (a). c) For the root node of your constructed tree in part (a), show the impurity after split (cf. slides 18,19,29 and 30 of the decision tree lecture notes)|
