Question

Write the claim below as a mathematical statement. State the null and alternative hypotheses and identify which represents the claim."An amusement park claims that the mean daily attendance at the park is at least 20,000 people."

Answer 1

Answer with explanation:

Given Claim : An amusement park claims that the mean daily attendance at the park is at least 20,000 people.

Let $\mu$ represents the mean daily attendance at the park.

Then , the set of hypothesis will be :-

Null hypothesis : $H_0:\mu\geq20,000$  ( It always takes equality sign )

Alternative hypothesis : $H_1:\mu<20,000$  (Just opposite of null hypothesis)

Here null hypothesis represents the claim.
