Suppose that you wish to perform a chi-square test of independence. The two variables under consideration are sex and blood type. True or false, if the two variables are not associated, we would expect that in the sample, the number of women with a given blood type would be roughly equal to the number of men with the same blood type? If the statement is false, rewrite it so that it is true.
