Statistics Hypo problem

You would construct two histograms (one for the total practice cost for Invisalign and one for the traditional treatment patient group)  your hypotheisis test would also focus on the difference between these two groups- looking at the mean cost for the two groups and the hypo test for the difference between the means.

The data is attached and there are hidden fields if you need more data to work from. 

The question we are testing is : 

The question I will be answering is whether traditional braces is a cost effective way to treat patients while comparing it to that of new technology clear aligner treatment costs. I plan on gathering financial data of the costs incurred per patient in each type of treatment and doing a cost comparison.
