Question

Quizplus · Accepted Answer

The problem involves multiple categories and frequencies, making it an example of a multinomial population. A multinomial distribution is used when there are more than two categories, and each observation falls into one of those categories. The problem does not mention anything about normal or Poisson distributions, and there is no indication that we are testing for independence between variables.
