Chapter 11.6, Problem 24HP

To determine

Write a brief summary of findings.

Answer to Problem 24HP

The claim is $\mu =3$ and it is a null hypothesis as it is an equality, the alternative hypothesis is $\mu \ne 3$ which is the compliment of the null hypothesis.

Explanation of Solution

Given information:

Design and conduct your own research study, and draw conclusions based on the results of a hypothesis test,

Calculation:

Hypothsis test is used to make a specific claim about the mean. The null hypothsis is represented by $H_0$ is a statement of equality used to be tested and alternative hypothesis by $H_a$ is a statement of equality which is compliment of the null hypothesis.

An observer observes a building will take $3$ minutes to get destroyed in earthquake of scale $8.0$ .

The claim is of $3$ minutes, so the null and alternative has been shown as

  $\begin{array}{l}{H}_0:\mu =3\\ H_a:\mu \ne 3\end{array}$

The claim is $\mu =3$ and it is a null hypothesis as it is an equality, the alternative hypothesis is $\mu \ne 3$ which is the compliment of the null hypothesis.
