Discussion 1

Submit the Milestone Two Worksheet, In this milestone, you will address the following:

Indicate sample size (n = ?) and describe what consequence(s) this sample size will have on your analyses and on your reporting of results.
Using the Choose Your Test document, select a statistical procedure appropriate to your scenario/data. Explain why you selected that test, linking features of the scenario/data to information from the Choose Your Test document.

Note: This milestone addresses Section II, parts A and B only. You will do the calculations for Section II parts C, D, E, and F as you complete your final project.

I must used the book as a reference because my professor say I need to add more academic information that shows your knowledge of the course materials

In statistical hypothesis testing, the null hypothesis and the alternative hypothesis are two mutually exclusive statements used to test a statistical claim about a population or sample. The null hypothesis is the statement that there is no significant difference or effect between two or more groups, while the alternative hypothesis is the opposite of the null hypothesis and states that there is a significant difference or effect between two or more groups.

For example, in a study comparing the effectiveness of two different types of medication for a particular condition, the null hypothesis might be that there is no significant difference in effectiveness between the two medications, while the alternative would be that one medication is more effective than the other.
