Question: Check the correlation between the random variables X and Y generated by the random number generator of Computer Exercise 6.2 by computing the sample correlation

Check the correlation between the random variables X and Y generated by the random number generator of Computer Exercise 6.2 by computing the sample correlation coefficient of 1000 pairs according to the definition N Х (х, - йх) (Ү, — Ay) P(X,Y) = (N – 1) ô¡ô2 n=1

where
Âx : : ΣΧ. n=1 ΣΥ. Y, N n=1 ô? Σ (x, - Αx) n=1 -|2

and
N (, - ) (, Ay) P(X,Y) = (N 1) 2 n=1

N (, - ) (, Ay) P(X,Y) = (N 1) 2 n=1 x : : . n=1 . Y, N n=1 ? (x, - x) n=1 -|2
