9. A researcher wanted to know the nature of relationship between X and Y. What conclusion should she make if

Question

X 2 2 3 5
Y 2 4 4 6

Answer 1

y is not a function of x.

Answer 2

It's possible that for every number in the sequence (1st term, 2d term, etc) which we show as n, n+1, n+2, etc

y(sub n) = 2* x(sub n-1)

notice that each y is exactly twice the x that's over the preceding y

Answer 3

try plotting those points.........they don't make sense
