WebTo do this, simply note that, if we take the formula for Z, multiply both sides by σ, and then add µ to both sides, we get X = Zσ+ µ 4. The interpetation of Z values is straightforward. Since σ = 1, if Z = 2, the corresponding X value is exactly 2 … WebX ~ B(n, p) where n = 300 and p = 0.53. Because np > 5 and nq > 5, use the normal approximation to the binomial. The formulas for the mean and standard deviation are μ = np and σ = n p q n p q. The mean is 159, and the standard deviation is 8.6447. The random variable for the normal distribution is Y. Y ~ N(159, 8.6447).
