2. Consider the following five observations. You are to do all the parts of this exercise using only a calculator, or in an Excel spreadsheet. X x - X (x - x)2 y - y (x - x) ( y - D) 7.3 3 2.7 5 1.2 0 9 [v. = [x = Fill in the table. Put the sums in the last row. What are the sample means x and y? ge Calculate b, and by and state their interpretation. Compute )?_1 x7 , 27 1 x y;- Use the values to show that E(x - x)? = Ex; - nx2 and)(x - x) (y - y) = Exy - nxy d) Use the least squares estimates from part b to compute the fitted values of y and complete the remainder of the table below. Put the sums in the last row. X xe 7.3 3 2.7 1 5 2 1.2 0 9 4 Ine, = = = e) On graph paper (or a grid you draw), plot the points and sketch the fitted regression line " = bj + box;. Locate and plot the point of the means, (x, y). Does your fitted line pass through that point? f) Show that for the point of the means, (x, y), y = b, + b2x. g) Show that the mean of the predicted 9 is equal to y, the mean of the y. h) Compute 6. Compute the var(by)
