can either use hand write or done by python code.

a. Solve the following least squares problem using the normal equations: 0.16 0.10 0.26 10.28 2.02 1.29 [3.31 b. Now solve the same least squares problem again, but this time use the slightly perturbed right-hand side: 0.27 b0.25 3.33 c. Compare your results from parts (a) and (b). Can you explain this difference? Hint: Use the function np. 1inalg.cond to compute the condition number of AT A in different norms
