1. Obtain the linear regression of Y on X1, X2 (by hand-calculation). Do not use any code. Show all work. X1 X2 Y 0 0 3 0 1 3 1 0 20 1 1 20 (i) Write the regression equation. (Please draw a box /circle around the final equation or find a way to underline/highlight it so it stands out clearly.) (ii) If we view the above problem as one of binary classification, what would the classes (class labels / tags) be? (Again, box / highlight your answer.) If we use the result of this regression as a classifier, what will be the equation of the classifier? (Box / highlight, please.) (iv) For this particular data set, is the classifier, as obtained from the results of regression, unique? Just answer yeso (no further explanation needed)
