**David Q/R**, Friday, June 29, 2012 at 4:32pmX has a Normal (i.e. a Gaussian) probability distribution with mean 42.5 and a variance of 103.71. (That in turn means that it's got a standard deviation of sqrt(103.71) = 10.2, so since 95% of the distribution lies within the mean plus or minus about 2 standard deviations, 95% of the distribution lies between about 22.1 and 62.9)
