Applied Maths Fill in the blanks.

Not linearly related, because
The value of r_xy becomes 0 when the two variables are not linearly related to each other. It may happen that both the variables may be non-linearly related to each other. It does not necessarily imply that both are independent of each other.

+1 to-1, because
The range of simple correlation coefficient lies between +1 to-1 ie, - 1 <= r <= 1

\frac{k(n+1)}{100},because
In general, rank of k^th percentile is given by
P_{h}-\frac{k(n+1)}{100}
