Question

Describe the standard normal distribution. What are its characteristics? Choose the correct answer below. O A. The standard normal distribution is a normal probability distribution with mean u = 0 and standard deviation o = 1. Similar to any normal probability distribution, it has associated with it a bell-shaped curve, symmetric about a vertical line through u with inflection points at o and -o. The Z-scores theorem, along with a table of areas under this standard normal curve can be used to calculate probabilities for any normal distribution. OB. The standard normal distribution is a uniform probability distribution with mean u = 0 and standard deviation o = 1. Similar to any uniform probability distribution, it has associated with it a bell-shaped curve, symmetric about a vertical line through u with inflection points at o and -o. The Z-scores theorem, along with a table of areas under this standard normal curve can be used to calculate probabilities for any uniform distribution. The standard normal distribution is a normal probability distribution with mean u = 1 and standard deviation o=0. Similar to any normal probability distribution, it has associated with it a bell-shaped curve, symmetric about a vertical line through u with inflection points at o and -o. The Z-scores theorem, along with a table of areas under this standard normal curve can be used to calculate probabilities for any probability distribution, including uniform, exponential, and normal. Ос.

Answer 1

The standard normal distribution is normal distribution with mean =0 and standard deviation=1 similer to any normal probability distribution, it has associated with the Bell shaped curve symmetric about a vertical line through mu with inflection points at sigma and -SIGMA , The Z scores theorem , along with a table of areas under this standard normal curve can be used to calculate probabilities for any normal distribution

Answer is A.
