The value 5 pCi/L is considered the dividing line between safe and unsafe water. Would you recommend testing Ho: u = 5 versus H: H > 5 or Ho: = 5 versus H: u 5. A type II error in this case involves deciding the water is safe when it isn't. This is a very serious error, so a test which ensures that this error is highly unlikely is desirable. We prefer that the most serious error be a type II error because it can be explicitly controlled. O One should test Hn: H = 5 versus H: u 5. A type I error in this case involves deciding the water is safe when it isn't. This is a very serious error, so a test which ensures that this error is highly unlikely is desirable. We prefer that the most serious error be a type I error because it can be explicitly controlled.
