A group of ecology students investigated the population of wild garlic plants (Allium ursinum) in an L-shaped woodland clearing.

The dimensions of the clearing are shown in the diagram below:

Dimensions of the L-shaped woodland clearing

To estimate the population, the students:

  • Placed a 0.5 m×0.5 m0.5\text{ m} \times 0.5\text{ m}0.5 m×0.5 m square quadrat at 10 random coordinates within the clearing.
  • Counted the number of wild garlic plants inside each quadrat.

Their results are shown in the table below:
