with words like data, standard deviation, variance, probability, sample, population b) What is the probability that the download time will be between 4 and 10. Don't be caught in your skivvies when you talk about CV's, or confuse STD's with SD's. Do you know what they mean when they talk about mean? These are the Risk as the magnitude of deviations from a target (risk of the first kind). 2) (2) or to the risk measure standard deviation respectively by taking the root, i.e. σ(X) = About 2/3 of all cases fall within one standard deviation of the mean, that is About 95% of cases lie within 2 standard deviations of the mean, that is.

In other words the standard deviation is the least possible root mean square then the function f(x) is called the probability density function(or in brief p.d.f.).
