Predict the value for Y for the given X.
A sociologist is interested in relation between x = number of jobs and y= annual salary (in thousands of dollars) for people who live in the Nashville area. A random sample of 10 people employed in Nashville provided the following information:
|
X (Number of job changes)

∑x = 60; ∑y = 359; ∑x2= 13,013; ∑xy = 2231
If someone had x=2 job changes, what does minimum squares line predict for y, the annual salary?
