Can i use regression analysis for this problem?

#1
Hi
So im doing a study and i want to see if there is a trend here
What i got:
I got data that depends on if a certain animal is using a area (low use and high use)

what i want to do is find out if there is a significant difference between low & high area use of this animal

I got: Browsing proportions and distance to a thing in the environment

The goal is to tell if the animal (a predator) have any impact on the browsers in the forest.


sorry about the useless explanation, english is not my first language
could i use dummy-variables?
I got acess to minitab and excel
How should i do?
