Answer 1

Question 10

Here, we cannot find the exact correlation as we don't have numerical values, so option second and third can not be the answer

Instead we can find range of correlation

So, according to the graph, we can see that values are negatively sloped

That is value on y axis increases then value on x axis decreases

So, their is negative correlation between them

So, option first is best suitable for it.

That is, -1.0<R<-0.5

Question 11

Similarly, here we can see from graph there is positive slope

As value on y axis increases then value on x axis increases

And also we can draw a near linear straight line on the points

So, option third is best suitable for it

That is, 0.9<R<1.0
