Chapter 9, Problem 52E(choose chapter or problem)
Let \(Y_{1}, Y_{2}, \ldots, Y_{n}\) be a random sample from a population with density function
\(f(y \mid \theta)=\left\{\begin{array}{ll}\frac{3 y^{2}}{\theta^{3}}, & 0 \leq y \leq \theta \\0, & \text { elsewhere }\end{array}\right.\)
Show that \(Y_{(n)}=\max \left(Y_{1}, Y_{2}, \ldots, Y_{n}\right)\) is sufficient for \(\theta\).
