Webb23 maj 2024 · Thus, we have used MGF to obtain an expression for the first moment of an Exponential distribution. D) Normal Distribution. For the normal distribution, we’ll first discuss the case of standard normal, and then any normal distribution in general. A standard normal distribution has the mean equal to 0 and the variance equal to 1. Webbis approximately standard normal. To show this, we will assume a major result whose proof is well beyond the scope of this class.
