Question: Job Changes. A sociologist is interested in the relation between x = number of job changes and y = annual salary (in thousands of dollars) for people living in the Nashville area. A random sample of 10 people employed in Nashville provided the following information
\(\sum{x}\) = 60, \(\sum{y}\) = 359, \(\sum{{{x}^{2}}}\) = 442; \(\sum{{{y}^{2}}}\) = 13,013; \(\sum{xy}\) = 2231
- If someone had x = 2 job changes, what does the least-squares line predict for
the annual salary?
