"WebFor our coin problem, with the null hypothesis of $P_0 = 0.5$, we get $\alpha(6) = 0$, $\alpha(5) = 0.002$, $\alpha(4) = 0.02$, and $\alpha(3) = 0.11$. Thus, if we set our maximum acceptable probability of type-1 error $\alpha_z = 0.05$, we find that the we must set $\theta_r = 4$, and our rejection to be $Y \geq 9 ~or~Y \leq 1$.
