Let μ denote the true average radioactivity level (picocuries per liter). The value 5 pCi/L is considered the dividing line between safe and unsafe water. Would you recommend testing H0: μ = 5 versus Ha: μ > 5 or H0: μ = 5 versus Ha: μ < 5? Explain your reasoning. [Hint: Think about the consequences of a type I and type II error for each possibility.]
