Parameters vs. Statistics - Factor Variable

The dataset imagpop contains information about 10000 people from an imaginary population. One of the variables is cappun, which indicates whether the individual favors or opposes the death penalty. You can see the distribution of of this variable in the population in the row percents shown below:

rowPerc(xtabs(~cappun,data=imagpop))

## favor oppose Total
## 29.76 70.24 100.00

Suppose you are interested in the following

Research Question: What proportion of individuals in the imagpop population oppose capital punishment.

Suppose you decide to take a simple random sample of size 300. You can see the distribution of cappun in the sample below:

set.seed(2014)
mysamp<-popsamp(n=300,pop=imagpop)
rowPerc(xtabs(~cappun,data=mysamp))

## favor oppose Total
## 27.33 72.67 100.00
