Intro to Statistics Testing Questions

Are the final exams graded by instructors or just graded by a robot? How do you do a square root symbol on a computer keyboard? I’m missing answers on my quizes from not being able to type the correct notation and it’s very frustrating.

I discovered final exams are graded by the computer, not professors. To type a square root symbol, press Alt+251. I’ve e-mailed saylor regarding questions about why I’m missing questions on quizes when my answer is matching the answer they have and I have received ZERO response from them. Very disappointing.
