a$)$ Fit a best fit linear line for the data given in the Table above. Perform all the calculations by

analytical way.

b$)$ Write a MATLAB program to fit a linear regression for the set of data given in Table above and

then plot a graph with the data points as well as the linear line obtained.

c$)$ Now extend the code as such that the program is able to compute and display the coefficient of

determinant $(r^2).$
