A student measures g, the acceleration due to gravity, repeatedly and carefully, and gets an answer of 9.5 m/s2 with an error bar of 0.1 m/s2. Assuming the measurements are distributed normally with a central value of the accepted 9.8 m/s2, what would be the probability of his getting an answer that differs from 9.8 m/s2 by as much as (or more than) this?Assuming he made no mistakes, do you think that his experiment may have suffered from undetected systematic errors?
