Question

6. do Full body scan, Part II. The table below summarizes a data set we first encountered

Answer 1

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 proportions for each option would be the same.

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:

$\frac{170}{3} = 56.67$

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:

$\frac{914}{3} = 304.67$

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:

$\frac{53}{3} = 17.67$

Rounding, 18 Independents would be expected to not know or not answer.
