A news article reports that "Americans have differing views on two potentially inconvenient and invasive practices that airports could implement to uncover potential terrorist attacks." This news piece was based on a survey conducted among a random sample of 1,137 adults nationwide, where one of the questions on the survey was "Some airports are now using 'full-body' digital x-ray machines to electronically screen passengers in airport security lines. Do you think these new x-ray machines should or should not be used at airports?" Below is a summary of responses based on party affiliation.

The differences in each political group may be due to chance. Under the null hypothesis of independence between an individual's party affiliation and his support of full-body scans, how many Democrats would you expect to support (the answer choiceShould) the use of full- body scans? (Note: It may be useful to first add on an extra column for row totals before proceeding with the computations.)
