- The normal approximation to the binomial distribution works best when the number of trials is large, and when the binomial distribution is symmetrical (like the normal).
- A binomial distribution for which the number of trials n is large can well be approximated by a Poisson distribution when the probability of success, p, is:
- if x is a binomial random
- Which of the following is not a characteristic of a binomial experiment?
- The<br/>population inversion distribution is also called as() A: Negative<br/>temperature distribution B: Boltzmann<br/>distribution C: Thermal<br/>equilibrium distribution D: Maxwell<br/>distribution
