1. Randomly select 10 of the 20 data points from the grid.
2. Calculate the average number of sunflower plants per square meter for the selected sample.
3. Multiply the average by the total area (4 m x 4 m = 16 m²) to estimate the total population size.
4. Repeat steps 1-3 multiple times and calculate the mean of all estimates to improve accuracy.
5. Compare the estimated population size with the actual count from the full grid to assess sampling error.
