The president of a company was interested in determining whether there is a correlation between sales made by different sales teams and hours spent on employee training. These figures are shown.

Sales (in thousands)...............Training Hours

18..................................................7

33.................................................11

22.................................................11

39.................................................13

7....................................................4

Compute the correlation coefficient for the data. (Round your answer to 4 decimal places, the tolerance is +/-0.0001.)

The correlation coefficient is:?

What is your interpretation of this value? (Do not round your intermediate computations to answer this question.)

There is a (strong negative correlation) or (strong positive) or (a moderate positive) or (a moderate negative) or (no) linear association between sales and training hours.

Using the data, what would you expect sales to be if training was increased to eighteen hours? Use the linear regression model. (Round your answer to 2 decimal places, the tolerance is +/-0.01.) Sales = ____________ (in thousands)
