( 6 The Normal Approximation to the Binomial distribution. Under certain circumstances the normal distribution can be used as an approximation to the binomial distribution. If X ~ Bin(n,p) then E(X) = np and Var(X) = npq where q = 1-p. For large n and p not too small or too large (it can be n > 10, p close to or n > 30, p around )

The binomial distribution . . . The binomial distribution describes probabilities associated with repeated independent occurrences of events, with each event put into one of two categories, e.g., H vs. T. Suppose a bag of N coins is spilled. Suppose the variable is X, …

standard normal distribution. A standard normal distribution is a normal distribution rescaled to have μx = 0 and σx = 1. The pdf is: The ordinate of the standard normal curve is no longer called x, but z. Standardizing a normal distribution facilitates the computation of …

- Normal & standard normal distributions. 1. The Normal (Gaussian) Distribution. The normal (or Gaussian) distribution is a continuous probability distribution that frequently occurs in nature and has many practical applications in statistics. Many of its statistical uses derive from the fact that random errors often follow a normal distribution.
