Suppose we are sampling 58 observations from a normally distributed population where it is known that $\sigma$ = 24, but $\mu$ is unknown. We wish to test $H_0:\mu =params.m{u}_{n}ull$ against $H_1:\mu \ne params.m{u}_{n}ull$ at $\alpha =params.alpha$. Suppose, in reality, the null hypothesis is false and $\mu =params.m{u}_{t}rue$.
