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 = 0.
b. the mean and standard deviation have the values of μ = 1 and σ = 1.
c. the mean and standard deviation have the values of μ = 0 and σ = 1.
d. the mean and standard deviation have the values of μ = 0 and σ = 0.

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. This allows for the use of z - scores ($z=\frac{x - \mu}{\sigma}$) to standardize any normal distribution to the standard normal distribution for easier probability calculations.

Answer:

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