... What sample size for a given margin of error? Density of bacteria in solution: Measurement equipment has standard deviation σ = 1*106 bacteria/ml fluid. How many measurements should you make to obtain a margin of error of at most 0.5*106 bacteria/ml with a confidence level of 90%? For a 90% confide ...

... By ordering the original observations, and taking away the first k smallest observations and the first k largest obserations, the trimmed mean takes the arithmetic average of the resulting data. The idea of a trimmed mean is to eliminate outliers, or extreme observations that do not seem to have any ...
