Question

Answer 1

Answer #1

solution:

when the value of X2 (chi square) is zero

Option B is right answer

Expected frequency is equal to observed frequency

Explanation :

X2 = $\sum$ ( Oi - Ei ) / Ei

$\therefore$ for X2 to be zero

Oi - Ei has to be equal

option (B) is the correct answer

Answer 2
