Explain the purpose of hypothesis testing?

Use an example from life or work to illustrate the concepts.

Step 1: State the hypotheses by listing the hypothesis and alternative hypothesis

Step 2: Set the criteria for a decision

Step 3: Compute the test statistic

Step 4: Make a decision.

Explain a situation in life where someone presented with an argument based on a biased sample (e.g. cherry picking observations, etc.)

What happened in this scenario?

How would one handle it?

What does this tell us about sampling and making public arguments?
