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 = (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 sum of x = 60, sum of y = 359, Sum of x squared = 442, Sum of y squared - 13, 013, and Sum of xy = 2231.
d) If someone had x = 2 job changes, what does the least-squares line predict for y, the annual salary?
