Let X1 and X2 be independent random variables from a normal distribution with mean equal to one and standard deviation equal to one. Derive the distribution of (X2 + X1-2)^2/(X2 - X1)^2. If the resulting distribution is one of the special distributions, identify the distribution and all relevant parameters; otherwise, state "unknown".

Question

Let X1 and X2 be independent random variables from a normal
distribution with mean equal to one and standard deviation
equal to one. Derive the distribution of (X2 + X1-2)^2/(X2 -
X1)^2. If the resulting distribution is one of the special
distributions, identify the distribution and all relevant parameters;
otherwise, state "unknown".

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
