i don't know if this is right but it might be 1.91 x 10^25
Using the appropriate sample size formula, the minimum number of samples required is 267
<u>Using</u><u> </u><u>the</u><u> </u><u>relation</u><u> </u><u>:</u>
- N = [(Z² × pq) / e²]
- e = Error Margin = 0.06² = 0.0036
- p = 0.5
- q = 1 - 0.5 = 0.5
- Zcritical at 95% = 1.96
<u>Substituting the values into the equation</u> :
N = [(1.96² × (0.5 × 0.5)) / 0.0036]
N = (0.9604 / 0.0036)
N = 266.777
N = 267
Hence, the minimum number of samples required is 267

Answer:
Puddles of water seen after a rainstorm that are clouded with sediment suggest erosion is occurring whereas puddles of clear water are a sign of minimal erosion. Lighter colored soil seen overtime is also a sign of erosion but can be more difficult to identify.
