Question
A sausage making machine occasionally produces misshapen sausages. The odds of the machine producing 0, 1, 2, 3, 4, or 5 sausages are .09, .07, .1, .04, .12 and .02 respectively. Find the variance and standard deviation.
1 Find and square the mean (here .81). Set this number aside.
2 Make a probability distribution chart :
 Number of misshapper sausages X 0 1 2 3 4 5 Proability P(X) 0.09 0.07 0.1 0.04 0.12 0.02
3 Square the top number, X, and multiply it by the bottom number ,P(X).
4: Add all of the numbers together.
5$$\sqrt{Step\ 4-Step\ 1}$$= SD
