How do you do this by hand and then with Python?

Consider the following data set, where each sample consists of two numerical input variables, X and X2, as well as one numerical output variable, Y. i=1 i=2 i=3 i=4 i=5 X1i 1.3 5.2 100.8 2.7 3.1 X2i 5.1 3.8 4.2 1.1 -123.2 Y 3.1 2.9 1.4 4.1 3 Based on the above data set, complete the activities listed. How would you transform a new, unseen sample (X, Y2; Y) = (0.8, 5.5; 2.8)?
