A certain experiment produces the data $(1,1.8),(2,2.7),$ $(3,3.4),(4,3.8),(5,3.9) .$ Describe the model that produces a least-squares fit of these points by a function of the form $y=\beta_{1} x+\beta_{2} x^{2}$ 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 to be set for the product. a. Give the design matrix, the observation vector, and the unknown parameter vector. b. [M] Find the associated least-squares curve for the data.

00:01 Here, first of all to calculate the slope, the equation of the slope is the summation of x y divided by summation of x square.
00:20 Here, the answer equal to 10 .59 divided by 55 which is nearly equal to 0 .19 0 .1927...
