Our study is a quantitative research study, and we want to see if there is a significant difference between computer science graduates' efficiency and their freelance counterparts in programming. There are two independent groups which are the computer science graduates composed of 10 respondents and their counterparts, or those who does programming but never finished a degree, also composed of 10 respondents.

I need help in interpreting the data, using 2 sample t test or Mann Whitney U test.

Below is the link to the survey questions.
