You make five measurements of a particular wavelength, and you find you have some random noise. Your measurements are {12,10,8,11,14} all in mm. For calculating the mean and the standard deviation below, don't use the "mean" or "sigma" key on your calculator - show explicitly the sums you are doing.
a) what is the mean value for your five measurements?
b) what is the standard deviation?
c) What is the standard error on the mean
