Q3 (11 points)
You are a biologist studying bird species richness across various habitats in a national park. Concerned
about potential biases, you hypothesize that certain habitat characteristics, such as vegetation density
and elevation, might influence bird species richness estimates. To test this hypothesis, you decide to
conduct the study in six locations within the park and consider the vegetation density factor.
