Web5 de jun. de 2012 · For instance, sums of independent normal RVs are themselves normally distributed. Such reproductivity of the distribution is enjoyed only by a limited class of distributions (that is, binomial, gamma, Poisson). Many important results in the theory of statistics are founded on the assumption of a normal distribution. solutions to challenges faced by teachersWebSince we are given that the distribution of heights in 12 year old boys is normal, we know that 2 SDs above or below the sample mean will give us an interval containing approximately 95% of the heights in the sample. This interval would run from 64 – 2*5 to 64 + 2*5, or 54 inches to 74 inches.
