In a study of politics and marriage, Hersh and Ghitza (2018) investigated the prevalence of mixed partisan households. Data from 64 households in which both spouses identified with a major party showed the following:

30 households with both spouses Republican
25 households with both spouses Democrat
6 households with a Republican husband and a Democrat wife 3 households with a Democrat husband and a Republican wife

Is the proportion of voters who identify as Republican higher for married men (group 1) than for married women (group 2)?

A. Calculate the exact P-value associated with the nonparametric test that uses mcnemarExactDP in R for the difference of dependent proportions.

B. The normal approximation to McNemar’s test produces a test statistic of z = 1. Compare the P-value of that test with the result from part (A) of problem AA.3 and briefly comment on the importance of using exact nonparametric procedures when normal theory assumptions are not met.

C. Briefly explain why the samples of men (group 1) and women (group 2) are dependent for this sampling design.
