Question

4. Suppose $X \sim U([0, \alpha])$ and $Y \sim U([0, \beta])$ are independent and $\alpha, \beta > 1$ are unknown. Define the distribution $Z = X + Y$. Suppose we are given $n$ independent samples $Z_1, \dots, Z_n \sim Z$. (Note that we are only given samples from Z, not from either X and Y.) Compute the method of moments estimators for $\alpha$ and $\beta$.
