Using the independence between an individual's party affiliation and his support of full-body scans, it is found that:
a) 57 Republicans would be expected to not support the use of full-body scans.
b) 305 Democrats would be expected to support the use of full-body scans.
c) 18 Independents would be expected to not know or not answer.
The independence between an individual's party affiliation and his support of full-body scans means that no matter the political party, the <u>proportions for each option would be the same.</u>
In the sample, there are 318 + 369 + 450 = 1137 people.
Item a:
- 38 + 55 + 77 = 170 people do not support the use of full-body scans.
- They should be equally divided between parties, hence:
Rounding, 57 Republicans would be expected to not support the use of full-body scans.
Item b:
264 + 299 + 351 = 914 people support the use of full-body scans, hence:
Rounding, 305 Democrats would be expected to support the use of full-body scans.
Item c:
16 + 15 + 22 = 53 people do not know or do not answer, hence:
Rounding, 18 Independents would be expected to not know or not answer.
