Question

The issue of capital punishment is a hotly debated topic. Do more Republicans than Democrats support capital punishment? A researcher randomly selects 100 republicans and 100 democrats and asks them if they support or do not support capital punishment. In this problem, we want to make inferences about:

A. one meanB. comparing means from dependent samplesC. comparing means from two independent samplesD. one proportionE. comparing proportions from two independent samplesF. comparing proportions from dependent samples

Answer 1

E. comparing proportions from two independent samples

Explanation:

First of all, we have two different populations: Republicans (group A) and Democrats (group B). We want to be able to compare if group A favors/likes certain policy more than group B. In order to do so, we must take independent samples from each population. Only after we have processed our data and calculated the results, can we compare between both groups.
