2. Homework Equations standard deviation= [tex] : s^2=\frac{\sum_{i=1}^n(x_i -\overline{x})}{n-1}[/tex] Actually the standard deviation is the square root of this expression.
3. I can use a statistics package like minitab or excell to solve this but how would I do it my hand? where would I start?[/b]
