Question: Sociology: 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:

∑x = 60; ∑y = 359; ∑x² = 13,013; ∑xy = 2231

(d) If someone had x = 2 job changes, what does the least-squares line predict for y, the annual salary?
