Reconsider the previous exercise, along with this additional information: 16 senators are women Democrats.
a. Produce a 2 × 2 table that classifies senators in the 2014 U.S. Senate according to party and sex of senator. Provide the relevant proportion(s) to answer the following questions:
b. Are most senators Republicans?
c. Are most Democrat senators women?
d. Are most women senators Democrats?

Data from previous question

The 2014 U.S. Senate consists of 80 men and 20 women. The 2014 U.S. Senate consists of 45 Republicans and 55 Democrats (counting 2 Independents as Democrats because they vote with Democrats more than with Republicans). What additional information do you need in order to produce a 2 × 2 table and investigate whether there is an association between sex and party?
