Question

To compare the proportion of right-handed students in the sample to those in the population, create two pie charts, one for handedness in the population and one for handedness in the random sample.

Answer 1

Suppose that 10% students are not right - handed. For population size 100 the pie chart will be:

Let we select 10% of sample :

Suppose that 10% students are not right - handed. For sample size 10 the pie chart will be:

Here are the R code used for this :

> pie(c(10,90),labels=c("NOT RIGHT HANDEDNESS","RIGHT HANDEDNESS"),main="Pie Chart forproportion of right-handed students those in the population" )
> pie(c(10,90),labels=c("sample selected"))

pie(c(1,9,90),labels=c("NOT RIGHT HANDEDNESS","RIGHT HANDEDNESS"),main="Pie Chart for proportion of right-handed students those in the sample" )
