Entomologists studying red ant habitats measured the number of
ant colonies per square mile identified at two randomly selected
state parks, under three densities of tree growth (sparse, average,
or dense growth). Use a significance level of alpha = .05.
a) Does a significant difference exist in the number of
ant colonies per square mile under the three densities of tree
growth (sparse, average, or dense growth)? If so, is a follow-up
test needed for further investigation? Explain.
b) Does a significant difference exist in the number of
ant colonies per square mile identified at the 2 state park sites?
Explain. If so, is a follow-up test needed for further
investigation? Explain.
