Question

Describe how you could use hypothesis testing to help make a decision in your current job, a past job, or a life situation. Include a description of the decision, what would be the null and alternative hypotheses, and how data could ideally be collected to test the hypotheses.

**Answers must be at least 2 paragraphs**

Answer 1

Given data:  

Describe how you could use hypothesis testing to help make a decision in your current job, a past job, or a life situation.

Solution:  

Suppose if we want to know the validity of a claim. In that case, we will consider an example a team that is working on a project where the team had to find out the lifespan of humans. The team assumes that lifespan will be 79years. And, this claim should be tested by us, we gather the information about the project and conduct a survey.

According to the survey, we observe the lifespan of a group of people and take the data, now we will determine the lifespan of humans. Here is the hypothesis :

Let, sample: {72,70,50,30,86,.........} be the data collected through survey

H₀ :(null hypothesis) mu=79

The lifespan of humans is 79 years.

And,

H_a :(alternative hypothesis) mu<79 or mu>79

The lifespan of humans will be less than 79   (or)

the lifespan of humans will be greater than 79

  Hence, This is the null and alternative hypothesis that will be obtained from the observed data collected through the survey. Now we can conclude the lifespan of humans.
