Please explain your work and reasoning:
Let X be a random variable, normally distributed with mean 100 and variance 64.
Mean = μ = 100,
Variance = σ2 = 64,
Standard Deviation = σ = 8.
1. If there are two random variables, X1 and X2, independent of each other, and each …
The distribution of the sum and difference of two normal distributions is discussed. Three problems solved.
