Title: AS physic uncertainty question
Post by: tmisterr on January 28, 2010, 04:02:21 pm

there this question thats really not hard but is itching my mind like a flea on rampage!
An ammter has an unvertainty of +-1.5% +-2 digits. The ammeter fluctuates between 1.58 and 2.04 A. What is the most likely value for the current and what is the uncertainty (this part i've done) but they give the most likely value as 2.01! how did they do it? ANY1? ASTAR?

Typo. I think 1.58 should be 1.98
