A marine biologist is investigating microplastic concentrations in the sediment of a tidal estuary. To obtain representative data, the biologist maps out the entire estuary and divides it into exactly 75 distinct, non-overlapping sampling zones. Due to budget and time constraints, core sediment samples can only be collected and analyzed from 8 of these zones.
Explain how the marine biologist could select the 8 sampling zones using simple random sampling.
