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.

(c) Find the sample correlation coefficient
r
and the coefficient of determination. (Round your answers to three decimal places.)

What percentage of variation in
y
is explained by the least-squares model? (Round your answer to one decimal place.)
%


(d) If someone had
x
= 2 job changes, what does the least-squares line predict for
y, the annual salary? (Round your answer to two decimal places.)
