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 30 50 28 50 25
y 2 2 6 5 9 3

Complete parts (a) through (e), given Σx = 196, Σy = 27, Σx2 = 7478, Σy2 = 159, Σxy = 1051, and r ≈ 0.842.

(a) Draw a scatter diagram displaying the data.
 
(b)Graph the least-squares line. Be sure to plot the point (x, y) as a point on the line.
 
(c)For a neighborhood with x = 40 hundred jobs, how many are predicted to be entry level jobs? (Round your answer to two decimal places.)
