A)binomial distribution
B)Poisson distribution
C)normal distribution
D)hypergeometric probability distribution

Question

Quizplus · Accepted Answer

The Poisson distribution is appropriate when dealing with the number of occurrences of an event over a specified interval of time or space, assuming that the events occur at a constant rate and are independent of each other. The binomial distribution is appropriate when dealing with a fixed number of independent trials that have only two possible outcomes. The normal distribution is appropriate for continuous variables and assumes a symmetric, bell-shaped distribution. The hypergeometric probability distribution is appropriate when dealing with sampling without replacement from a finite population with two types of objects.
