Question

If the alternate hypothesis of an experiment is “The true mean height of the giraffes is more than 15 feet” what is the null hypothesis?

Answer 1

Answer: "The true mean height of the giraffes is less than or equal to 15 feet".

Explanation:

A hypothesis in a statement that is made about a statistical parameter of a population.

A null hypothesis
`H_0` is usually the hypothesis that is tried to reject by an alternate hypothesis
`H_a`

In this case
`H_a` is:

"The true mean height of the giraffes is more than 15 feet".

Therefore, for this case, the null hypothesis must be:

"The true mean height of the giraffes is less than or equal to 15 feet".
