Hello! So...
We are given the following:
Solve for x.

====================
1. Group the like terms.
====================
2. Add similar elements (
).
====================
3. Subtract 23 from both sides.
====================
4. Simplify.
====================
5. Divide both sides by 4.
====================
6. Simplify.
(aka. Option A)
====================
Hope this helps!
Answer:
H0: μ = 5 versus Ha: μ < 5.
Step-by-step explanation:
Given:
μ = true average radioactivity level(picocuries per liter)
5 pCi/L = dividing line between safe and unsafe water
The recommended test here is to test the null hypothesis, H0: μ = 5 against the alternative hypothesis Ha: μ < 5.
A type I error, is an error where the null hypothesis, H0 is rejected when it is true.
We know type I error can be controlled, so safer option which is to test H0: μ = 5 vs Ha: μ < 5 is recommended.
Here, a type I error involves declaring the water is safe when it is not safe. A test which ensures that this error is highly unlikely is desirable because this is a very serious error. We prefer that the most serious error be a type I error because it can be explicitly controlled.
