(a) Use least-squares regression to fit a linear polynomial to the data given in the table below: 2 4 6. 8 10 411.41 412.54 413.29 414.25 414.17 415.39 415.71 416.80 416.68 12 14 16 18 Calculate the standard deviation for the regression line. Then, use the fitted linear formula to estimate the y-value at x-14.6. Round all your computations to 6 decimal points. (b) Repeat part (a) but with using the general least-squares estimation approach (i.e., the one implementing the matrix-vector fornm). Comment on the vector of residuals. Hint: You do not need to develop a program for this problem. Solve it manually and submit,
