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. 10 10 3 (number of job changes) 5 y (Salary in $1000) 4 3 6 1 5 35 32 32 32 38 9 43 37 37 40 33 LUSE SALT In this setting we have Ex= 56, Ey = 359, Ex² = 402, y2 = 13,017, and Exy = 2091. (a) Find x, y, b, and the equation of the least-squares line. (Round your answers for x and y to two decimal places.
