How does a multinomial distribution differ from a binomial distribution?
a. A binomial has only two possible categories and a multinomial can have more.
b. A binomial has a fixed number of n trials. A multinomial has a fixed number of nk trials, where k is the number of categories.
c. The probabilities in a binomial distribution are always p and 1 - p. The trials in a multinomial distribution are always p/k and (1 - p/k).
d. All of these choices are true.

Q. 3How do you calculate the expected frequency for one cell in a goodness-of-fit test?

b. Use the total number of observations divided by the number of categories.
c. Multiply the specified proportion for that cell (found in H0) by the total sample size.
d. None of these choices.
