Question

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	17	32	52	28	50	25
y	1	2	7	5	9	3

Complete parts (a) through (e) after verifying that Σx = 204, Σy = 27, Σx² = 7,926, Σy² = 169, Σxy = 1,110, and r ≈ 0.8854.

A) Find x (in hundreds). (Round your answer to four decimal places.)
x =
hundred jobs
Find y (in hundreds). (Round your answer to four decimal places.)
y =
hundred jobs
Find the equation of the least-squares line ŷ = a + bx. (Round your numerical values to four decimal places.)
ŷ =
