Please find and graph the least squares polynomials of degrees 1,2, 3 by using python

1. Find the least squares polynomials of degrees 1, 2, 3, and 4 for the data: X; 0.0 0.2 0.5 0.7 1.1 1.5 1.9 2.3 2.8 3.1 Vi 2.56 13.18 30.11 42.05 67.53 95.14 124.87 156.73 199.50 226.72 In each case compute E, the sum of the squared errors, and provide a graph of the data and the best fit polynomial. Which polynomial would you use to represent the data? Why
