Option first "0; it represents no correlation between x and y" is correct there is no relation between x and y.
<h3>What is correlation?</h3>It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
We have:
Age (years) (x) 15 21 17 22 16 19 18
Number of questions they could answer(y) 17 17 17 17 17 17 17
As we can see all y values are the same.
n∑y² = 7(2023) = 14161
(∑y)² = 119² = 14161
If we put the value of the above data the value will become undefined.
Thus, option first "0; it represents no correlation between x and y" is correct there is no relation between x and y.
