Sociology: Job Changes A sociologist is interested in the relation between x 5 number of job changes and y 5 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 (Number of job changes) 4 7 5 6 1 5 9 10 10 3 y (Salary in $1000) 33 37 34 32 32 38 43 37 40 33 Complete parts

(a) through (c), given x 5 60; y 5 359; x2 5 442; y2 5 13,013; xy 5 2231

(d) If someone had x 5 2 job changes, what does the least-squares line predict for y, the annual salary?
