Please Solve (B)

Question 1 (Regression and Interpolation) Given the data sets for $$x$$ and $$y$$ variables as in Table Q1 it is required to do the following: (a) find a regression of the given data using following methods: (i) fit straight line to the data using least square root (ii) fit data with $$2^{\text{nd }}$$ order polynomial (b) find the interpolation of the data using following methods: (i) Quadratic Newton divided-difference interpolating polynomial (ii) $$2^{\text{nd }}$$ order Lagrange interpolation method (iii) line spline method
