Let m 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 versus or versus Ha H : m , 5? 0 H0: m 5 5 Ha: m . 5 : m 5 5 m , 100 Ha H0: m 5 100 : m . 100 H0: p1 2 p2 5 2.1, Ha: p1 2 p2 , 2.1 H0: s1/s2 5 1, Ha: s1/s2 2 1 H0: m 5 120, Ha: m 5 150 Explain your reasoning. [Hint: Think about the consequences of a type I and type II error for each possibility.]
