1) You make five measurements of a particular wavelength, and you find you have some random noise. Your measurements are 244, 251, 248, 248, 246 nm. For the calculations below do not use the pre-programmed functions of your calculator - show the sums you are doing explicitly.
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?
