Question

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 _{(number of job changes)}	5	3	4	6	1	5	9	10	10	3
y _{(Salary in $1000)}	36	35	38	32	32	38	43	37	40	33

In this setting we have Σx = 56, Σy = 364, Σx² = 402, Σy² = 13,364, and Σxy = 2107.

(a) Find x, y, b, and the equation of the least-squares line. (Round your answers for x and y to two decimal places. Round your least-squares estimates to four decimal places.)
