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.
Answer:
Step-by-step explanation:
One number would be
9.31
The 3 in this number is 3/10
The 3 in the given number is 3/100
3/10 is 10 times bigger than 3/100
3/10 = 0.3
3/100 = 0.03
0.03 * x = 0.3 Divide both sides by 0.03
0.03/0.03 x = 0.3/0.03
x = 10
