Answer 1

Answer:

- 0.21

Step-by-step explanation:

The correct answer will be option B.

-0.21

The correlation coefficient is a number between  and  that represent the linear dependence of two variables or sets of data

Let

A ( 1 , 4 ) B ( 2 , 1.5 ) C ( 3, 3) D ( 4,4 ) E ( 5,2 )

When we use the function CORREL in an Excel tool. The correlation co - efficient can easily be calculated . The calculation is given in the following image as it can be easily found in Excel.
