In the Australian population, approximately 9% have extras-only private health coverage.

Scenario 1. You can take a desired samplex of size 20 from the population, calculate the associated sample proportions, plot them, and summarise your observations.

From your work in the previous chapter, and your knowledge of binomial graphs, you should already have an idea of what might be observed. What shape do you think the graph will have?

Use the technology to simulate the problem for multiple samples and sizes to demonstrate the investigation.

You can use the following portal to conduct the simulation.
