A-Let x be the average number of employees in a group health insurance plan, and let y be the average administrative cost as a percentage of claims.
| x | 3 | 7 | 15 | 34 | 73 |
| y | 40 | 35 | 30 | 28 | 16 |
Use a calculator to verify that Σx = 132, Σx2 = 6768, Σy = 149, Σy2 = 4765, and Σxy = 2935. Compute r. (Round your answer to four decimal places.)
B-Is the magnitude of an earthquake related to the depth below the surface at which the quake occurs? Let x be the magnitude of an earthquake (on the Richter scale), and let y be the depth (in kilometers) of the quake below the surface at the epicenter.
| x | 3.2 | 4.0 | 3.3 | 4.5 | 2.6 | 3.2 | 3.4 |
| y | 5.2 | 10.3 | 11.2 | 10.0 | 7.9 | 3.9 | 5.5 |
Use a calculator to verify that Σx = 24.2, Σx2 = 85.94, Σy = 54.0, Σy2 = 466.44 and Σxy = 191.52.
Compute r. (Round your answer to four decimal places.)
