Question

what requirements are necessary for a normal probability distribution to be a standard normal probability distribution? choose the correct answer below. a. the mean and standard deviation have the values of μ = 1 and σ = 1. b. the mean and standard deviation have the values of μ = 0 and σ = 0. c. the mean and standard deviation have the values of μ = 1 and σ = 0. d. the mean and standard deviation have the values of μ = 0 and σ = 1.

Explanation:

A standard - normal distribution is a special case of the normal distribution. By definition, it has a mean ($\mu$) of 0 and a standard deviation ($\sigma$) of 1.

Answer:

D. The mean and standard deviation have the values of $\mu = 0$ and $\sigma = 1$.
