Chapter 9, Problem 53E(choose chapter or problem)
Let \(Y_{1}, Y_{2}, \ldots, Y_{n}\) be a random sample from a population with density function
\(f(y \mid \theta)=\left\{\begin{array}{ll}\frac{2 \theta^{2}}{y^{3}} & \theta<y<\infty \\0, & \text { elsewhere }\end{array}\right.\)
Show that \(Y_{(n)}=\min \left(Y_{1}, Y_{2}, \ldots, Y_{n}\right)\) is sufficient for \(\theta\).

f(y | theta) = {frac{2 theta^{2}}{y^{3}} & theta < y < infty 0, & elsewhere }.
Y_(n) = min (Y_1, Y_2, …., Y_n)
