Using the given statement in bold.

A biogeographer wishes to analyze global changes in the spatial extent and nature of tropical rain forests. As part of this study, a detailed ecological examination of a sample of rain forest sites is necessary.

1.List one research hypothesis, in both written form and mathematical symbols, that could result from this research question.Remember that this hypothesis should be stated as a difference of means or proportions.This is the alternate hypothesis.

H_A =

2.State the null hypotheses, in both written form and mathematical symbols, for this problem that would form the basis for the hypothesis test using the single sample.

H₀ =

3.Is the research data require a one sample difference of means Z test or t test, or a one sample difference of proportions?Why?

4.Is your problem set up as a one-tailed (directional) test or a two-tailed (non-directional) test?Explain your answer:
