1. for the following population of N=10 scores
14,6,8,3,9,12,1,6
a) sketch a histogram showing the population distribution
b) locate value of the population mean in your sketch and make an estimate of the standard deviation
c) compute sum of square (SS), variance, and standard deviation for the sample.
2. Calculate SS, variance and standard deviation for the following sample of n=4 SCORES,
4,0,1,1, ( NOTE: the computational formula works well with there scores)
