Customer Question

Doing a statistical analysis /...

Doing a statistical analysis / T-Test. I used a 5 point likert scale. I am looking at a "comfort level" for people. 1-very uncomfortable to 5-very comfortable. When analyzing the data, do I exclude those respondents that PRE intervention were a 5 "very comfortable" as they already were at the top, so therefore cannot show that they improved with the intervention?
