Find the value of the linear correlation coefficient r. The paired data below consist of the costs of advertising (in thousands of dollars) and the number of products sold (in thousands). Cost 9 2 3 4 2 5 9 10 Number 85 52 55 68 67 86 83 73

The value of the linear correlation coefficient, r, as calculated using Microsoft excel is: 0.708.

(See image attached below)

Therefore, the value of the linear correlation coefficient, r, as calculated using Microsoft excel is: 0.708.

Step-by-step explanation:

The calculation of linear correlation coefficient r is shown below:-

Cost        Number

9                 85

2                 52

3                  55

4                  68

2                  67

5                  86

9                  83

10                 73

linear correlation coefficient r = 0.70772136

or

= 0.708
