Standard Normal Distribution.

1.	Standard Normal Distribution.
Answer» The probability distribution of standard normal variable Z is called standard normal distribution. It’s density function is as follows: \(f(z) = \frac{1}{2π}e^{−\frac{1}{2}z^2}\,-∞ < z < ∞\) where z = \(\frac{x−μ}{σ}\) Mean of standard normal distribution = 0, Variance = 1 ∴ S.d. = 1

Answer»

The probability distribution of standard normal variable Z is called standard normal distribution. It’s density function is as follows:

\(f(z) = \frac{1}{2π}e^{−\frac{1}{2}z^2}\,-∞ < z < ∞\)

where z = \(\frac{x−μ}{σ}\)

Mean of standard normal distribution = 0, Variance = 1 ∴ S.d. = 1
