Question

A certain experiment produces the data (1, 1.9), (2,2.7), (3,3.2), (4, 3.5), and (5, 3.8). Describe the madel that produces a least-squares fit of these paints by a function of the formy22. Such a function might arise, for example, as the revenue from the sale of x units of a product, when the amount offered for sale affects the price set for the product. a. Give the design matrix and observation vector for the unknown parameter vector B b. Find the associated least-squares curve for the data a. The design matrix is X- The observation vector is y b, The least-squares curve for the data is given by the function y.D.OR P1 P2 x- (Round to two decimal places as needed.)
