2.7 Optional: Sampling

This question is optional; e.g., if you need more practice, or you are studying for the exam.

Suppose we needed a sample of \(80\) vehicles parked at UniSC, and we wish to determine the proportion displaying P-plates.

Determine a useful way to find a suitable representative sample. The map below of the UniSC Sippy Downs campus may prove helpful (where areas labelled P are car parks).
