1.You have one dependent variable, which is continuous. You have one independent variable, which is categorical. The independent variable has 3 levels/categories, and the same entities are in each category.

Which statistical test should you use (note that you can only select one test)? (5 points)

2.You have three continuous dependent variables and two categorical independent variables.

Which statistical test should you use (note that you can only select one test)? (5 points)

3.Now imagine you are in my face-to-face class, and, as I have done in the past with previous classes, I ask the class to participate in activity in which they will measure their resting heart rate in beats per minute. I then ask the students to stand up and sit back down after which they remeasure their heart rate. Thus, everyone provides a "resting" heart rate and a "standing" heart rate. We as a class then proceed to determine whether standing up will significantly raise heart rate.

Which statistical test should you use (2 points)? Next, explain why you selected the test you did by going through the steps in the flow chart for the dependent variable (3 points) as well as for the independent variable (5 points)? In your explanation, be sure to clearly identify what exactly the dependent and independent variables are in addition to noting what the levels of the independent variable are.

4.Which type of exercise is associated with the healthiest LDL cholesterol level: Walking, Running, or Powerlifting? Imagine you are able to recruit 90 participants for your study each of whom have self-identified their exercises as Walking (n=30), Running (n=30), or Powerlifting (n=30) and have been on the exercise for at least three months. You measure their LDL cholesterol to determine which type of exercise is best.

Which statistical test should you use (2 points)? Next, explain why you selected the test you did by going through the steps in the flow chart for the dependent variable (3 points) as well as for the independent variable (5 points)?
