What is positive correlation?

"A positive correlation exists when one variable tends to increase/ decrease as the other variable increase/decreases."

For given question,

A positive correlation between the variables k and l.

l is 150 when k is 7

We need to find the value of l when k = 14.

 l              k

150           7

?              14

We find the value of l.

$l=\frac{14\times 150}{7}\\\\ l=2\times 150\\\\l=300$

Therefore, the value of l is 300 when k is 14.

The correct answer is an option (A)
