Question

10. Match problems to procedures

a. A multinomial probability distribution describes the distribution of counts across multiple levels of a variable. A special case is the binomial discrete probability distribution. For each level of a variable, which is common to multiple populations, equality of distributions can be tested.

b. Do contingency table classification values matter?

c. Does the data validate the normal probability distribution assumption?

d. Data were gathered in an experiment comparing the effects of three insecticides in controlling a certain species of parasitic beetle. Each observation represents the number of such insects found dead in a certain fixed area treated with an insecticide.

                (1) ANOVA

                (2) Chi-square test of homogeneity

                (3) Chi-square test of independence

                (4) Chi-square test of goodness of fit
