In a Poisson probability distribution __________________?
Correct answer: A. The mean and variance of the distribution are same (equal)
- A. The mean and variance of the distribution are same (equal)
- B. The probability of success is always greater than 5
- C. The number of trials is always less than 5
- D. it always contains a contingency table
Explanation
For a Poisson distribution, the single parameter λ determines both its mean and variance, so each equals λ. The other options describe neither a defining property nor a requirement of the Poisson model.
