Write a 525- to 750-word paper that addresses the following for your chosen scenario:
Clearly define the problem or issue you are addressing. Provide a brief background of any research you have found that might affect your research hypothesis.
Create a research hypothesis based on the information provided in each scenario. You have been given a data set (Microsoft® Excel® document) with two sets of interval data (just the numbers, as you must decide what they represent, such as method A results or method B results).
This means you are going to test one thing against another, such as which method works best (step 1 of the steps to hypothesis testing). State the null and research hypotheses. Explain whether these hypotheses require a one-tailed test or two-tailed test, and explain your rationale.
Describe the sample you will use. Sample size will be 30 for each group, which are provided in your data set. Explain what type of sampling you selected.
