In performing statistical comparisons for ground cover, results of randomly assigned line-point transects will be compared to the success standard (seventy percent ground cover at a ninety percent confidence statistical interval), as illustrated in the following example:
Null hypothesis: ground cover on release area >=70% ground cover.
Alternate hypothesis: ground cover on release area < 70% ground cover.
| sample results (x) | x2 | release area ground cover standard | |
| assume that it | 41% | 1681 | 70% |
| took 10 samples (n) | 72% | 5184 | |
| to achieve sample | 89% | 7921 | |
| adequacy | 42% | 1764 | |
| 69% | 4761 | ||
| 80% | 6400 | ||
| 42% | 1764 | ||
| 57% | 3249 | ||
| 77% | 5929 | ||
| 89% | 7921 | ||
| [SIGMA]x = 658% | [SIGMA]x2 = 46,574 |
Since 0.7 < 1.38, the null hypothesis is accepted; and it is accepted that the ground cover on the release area is greater than or equal to the target ground cover.
