I am testing my null hypothesis of $\mu=3$ against the alternative of $\mu >3$. $n=16$ and $\sigma=1$ and $\alpha=0.10$.
I am conflicted because it is a small sample size and I know the standard deviation. How do I decide which test to use given only this information? I initially solved with the t-test, but I am reading that you should not use it if you know the standard deviation.
