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.)
