Answer to Problem AP3.30CPT

Option (b) is the correct option.

Explanation of Solution

It is given that a survey by the school newspaper is conducted at the university to study about how they are planning to give the vote. Thus, by looking at the options, we can say that,

Option (a) is not true as total republican divided by the sample total is:

  $\frac{712}{1850}=38\%$ .

Option (c) is not correct as $\frac{78}{1037}=7.5\%$ not $11.2\%$ .

Option (d) is not true as $\frac{45}{106}=42.4\%$ not $44.6\%$ , those who are undecided are Independents.

Option (e) is not true as $\frac{78}{696}=11.2\%$ .

Thus, we conclude that option (b) is the correct option, as we are looking for Romney and diving by the total of political persuasion. As, we have,

Democrat: $\frac{78}{1037}=7.5\%$ .

Republican: $\frac{598}{712}=84\%$ .

Independent: $\frac{19}{101}=18.8\%$ .
