Answer:
Pseudogymnoascus destructans is the fungus that causes WNS in Bats.
First we'll divide the the bats into four groups as:
A = 29, B = 29, C = 29, D = 30 (Control)
The A group is exposed to a small amount of spores of Pseudogymnoascus destructans and data is collected.
The B group is exposed to a moderate amount of spores of Pseudogymnoascus destructans and data is collected.
The C group is exposed to a lethal amount of spores of Pseudogymnoascus destructans and data is collected.
The D group is exposed to nothing.
After collection of that data, the results about interpretation can be recorded using basic statistical analysis.
