Question

Is the statement H0 : µ = 9 a valid null hypothesis? Group of answer choices Yes, this is a statement that compares a parameter to a value Yes, this is a statement that compares two parameters No, equalities are not permitted in a null hypothesis No, there is no parameter contained in this statement

Answer 1

No, there is no parameter contained in this statement

Explanation:

Given that H0 : µ = 9

We have to check whether this is a valid null statement

Normally null hypothesis would have equal to sign and the value to be tested would be a statistic i.e. a measure characteristic of a sample.

So we create null hypothesis as sample mean = 9 or \mu or sample std deviation and so on.

Here population parameter mu is equated to 9

Hence not a valid null hypothesis.

No, there is no parameter contained in this statement
