Let \(X_1,\ldots ,X_n\) be independent and identically distributed with density function \[ h(t;\theta )=\theta t^{\theta -1}1\{0\leq t\leq 1\} \] for \(\theta >0\) unknown. Use the Neyman-Pearson Lemma to find the uniformly most powerful test of size \(\alpha \) for \(H_0:\theta =\theta _0\) versus \(H_a:\theta =\theta _1\), where \(\theta _1>\theta _0\).
