Question 4 Consider the following plot. X and Y are continuous variables, and G is binary. 10- 1' 5- G >1 0 O 0' o 1 _5. I O :2 a 2 a {5 X a} Design a model to predict Y. Write down the conditional expectation of Y. b} There are three labeled points (the triangles). The color of each matches group membership. For each point, is it a problematic outlier, an outlier, or neither? Defend your decision
