If u = 5 and S.D. = 2.5 then Binomial distribution are ________________?
Correct answer: B. Wrong
- A. Unequal
- B. Wrong
- C. Fair
- D. None of these
Explanation
For a binomial distribution, mean = np and variance = npq, so variance divided by mean must equal q. Here q = 2.5²/5 = 1.25, which is impossible because a probability cannot exceed 1; hence the stated values are invalid.
