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

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

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

Sales

Training
Hours

Explanation / Answer

The correlation coefficient is 0.93512214

There is an strong positive correlation between training hours and sales volume, apparently, the time invested in employees training is contributing to improve the sales volume.

Using a Linear Regression Model as : Y = m*X where Y are sales (thuosands) m is linear estimated coeficient and X is Training Hours to employees, lets calculate "m" that equals 3.242424, so:

Y = 3.242424 X = 3.242424 (18) = 58.36 thousands of items sold
