Answer the following 2 questions in your main post:

• What experience do you have with hypothesis testing? This can be as simple as you were given an amount of money and had to explain different ways to best utilize the money to make ends meet, to as complicated as a professional issue that needed to be solved.
• Which testing method—one-sample or two-sample parameter tests—is the better test to use to formulate an answer to a hypothesis? Explain.

Answer 1

Hypothesis testing refers to the process of making inferences or educated guesses about a particular parameter. This can either be done using statistics and sample data, or it can be done on the basis of an uncontrolled observational study.

You should do a two sample test if you are comparing two samples, each of which has variability that should be modeled. A one sample test would be if you were comparing the mean of a sample to some fixed value.
