We have given the number of possible values for two variables of a population. For each exercise, determine the maximum number of expected frequencies that can be less than 5 in order that Assumption 2 of Procedure 12.2 to be satisfied.

a b A AB 10 10 20 40 30


Procedure 12.2 

Purpose To perform a hypothesis test to decide whether two variables with are associated Assumptions

a. All expected frequencies are 1 or greater

b. At most 20% of the expected frequencies are less than 5

c. Simple random sample
