Properties of Correlation Coefficient,
1- A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.
2- A negative correlation means that if one variable gets bigger, the other variable tends to get smaller.
As in this graph x increases y gets decreased, so it is a negative co-relation. And the points are scattered more the line, so it is a moderate negative co-relation graph. (Please follow the attached picture herewith)
I think the answer is A!!!
If my memory does not remember wrong you have to multiply 1.63x1.84=2.9992 after this you have y=2.9992x, you have to substituted the x for 5 y=2.9992(5) and that will equal to y=14.996 and rounded will be 15 hope I was able to help
The answer in simplest form is 7/30
