An economist is studying the job market in Denver area neighborhoods. Let x represent the total number of jobs in a given neighborhood, and let y represent the number of entry-level jobs in the same neighborhood. A sample of six Denver neighborhoods gave the following information (units in hundreds of jobs). x 13 32 52 28 50 25 y 1 2 7 5 9 3   Complete parts (a) through (e), given Σx = 200, Σy = 27, Σx2 = 7806, Σy2 = 169, Σxy = 1106, and r ≈ 0.8855.   (a) Draw a scatter diagram displaying the data.   Verify the given sums Σx, Σy, Σx2, Σy2, Σxy, and the value of the sample correlation coefficient r. (Round your value for r to four decimal places.) Σx= Σy= Σx2= Σy2= Σxy= r= Find x, and y. Then find the equation of the least-squares line ŷ = a + bx. (Round your answers to four decimal places.)   x=
