You measure the distance, l, a projectile travels several times
using the same apparatus and find the following values (cm): 5.11,
4.89, 5.04, 4.94, 4.93, 5.06 and 5.09. Assuming that the errors are
random: a) What is the mean value forl? b) What is the standard
deviation for this data set? c) What is the uncertainty associated
with your best estimate forl? d) How should one report the result
of this measurement along with the uncertainty at the 95 %...
