Testing of hypothesis

1. The research hypothesis is: There are significant total mass changes in nucella lamellosa based on location.

2. The statistical null hypothesis is: Regardless of where they grow, the species total mass will not change.

3. The level of significance used is: P-0.05. There is a 5% probability due to chance.

4. Is the t-statistic greater than or less than the t for that level of significance? The calculated value of “T” is 0.55. There is a 55% chance that they are the same.

5. Do I accept or reject the statistical null hypothesis? 55% is larger than 5% so I do not reject the null hypothesis.

6. Do I accept or reject the research hypothesis? This is rejected.

7. Is this a one-tailed test or a two-tailed test? This is a two-tailed test with 59% falling in one direction.

8. Where was the data found? From a supplied database constructed from scientific observation.

9. How was the data collected? By taking weight measurements.

10. The sample being studied is “total mass” compared between two different locations.

11. What species? nucella lamellosa

12. Where do they live? Cantilever North and False Bay.

13. What program was used to conduct the analysis? Excel.
