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 | 13 | 32 | 48 | 28 | 50 | 25 |
| y | 2 | 3 | 6 | 5 | 9 | 3 |
Complete parts (a) through (e), given Σx = 196, Σy = 28, Σx2 = 7406, Σy2 = 164, Σxy = 1075, and r ≈ 0.877.(
b) Verify the given sums Σx, Σy, Σx2, Σy2, Σxy, and the value of the sample
Σx =
Σy =
Σx2 =
