Description
Assignment Scenario that you need to answer: Suppose you administer a certain aptitude test to a random sample of 9 students in your high school, and the average score is 105. Assume a standard deviation ofσ = 15 for the test. We want to test that the average aptitude test is more than 100 at the α= 0.05level. List out the five steps in hypothesis testing and be sure to write sentences explaining what you should do using the information given to you in the previous sentences.

Rasmussen College Exercise and Diet Outcomes Comparative Paper
Multiple factors can correlate to a single outcome. Using available health statistics, form an opinion on whether exercise or diet has a greater impact on weight lost.Present your findings as a persuasive report inclusive of data visualizations. The data visualizations should compare the two key factors, one being exercise and the other being diet. In a third category, include both exercise and diet. Then share insights regarding these three separate categories in terms of weight loss. A primary point of emphasis should be to clearly communicate the correlation or causation of exercise and diet on weight loss. You will need to look at details such as the type of exercise and amount of time spent. Also, consider factors of diet like types of foods eaten and portion sizes. This assignment should be 2-3 pages in length.
