Question 1. Let u 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 Ho: μ = 5 versus Ha: >5 or Ho : μ = 5 versus Ha: <5? Select the correct statement. (Hint: Think about the consequences of a type I and type II error for each possibility.] O One should test Ho: μ = 5 versus Ha μ< 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. One should test Ho : μ = 5 versus H₁ μ< 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.
