Wanted to confirm that I'm right because I still keep getting error on these questions.

1- Identify the variable that best belongs in the list indicated:showering frequency only,weight loss only, or both showering frequency and weight loss.Do not use the same variable more than once.

____Showering frequency only

____Weight loss only

____Both showering frequency and weight loss

A.Skin type (oily,dry,etc.)

B.Exercise routine

C.Diet

2-Identify the confounding, explanatory, and response variables.

Explanatory____

Response_____

Confounding_____

A.Showering frequency

B.Diet

C.Exercise routine

D.Skin type (oily, dry,etc.)

E.Weight loss

3-A description of confounding must explain how the confounding variable influences both the explanatory and response variables. Which of these statements does that?

A. Exercise routine influences shower frequencybecause exercising makes us sweaty, and influencesweight loss because it burns calories.Exercise routine is the reason we see an increase in shower frequency tend to accompany an increase in weight loss.

B. Diet influences weight loss, because our bodies need calories in order to create and maintain body fat. Because diet has such a strong impact on weight loss, we can't really say that shower frequency causes weight loss.

C. Skin type influences how frequently we shower, because people with dry skin shouldn't shower as often as people with oily skin.Because there are other factors at play, we can't really say that shower frequency influences weight loss.

D. The study was performed on a sample, and therefore we really can't conclude anything about the population.

4- In the Spankings and bullying example described in the handout,which of the following provides an explanation of confounding?Keep in mind thatan influence must be established from the confounding variableto both the explanatory and response variables in order to explain confounding. (Multiple Answers).

A. Children with ADHD may be more challenging to raise without spankings, and may tend to have anxieties that lead to bullying behavior in their older years.

B. Children who are bigger are more likely to be bullies because they can win fights with other kids.

C. Some parents will spank whether the child is acting out or not, and some kids will bully no matter how they were raised, so it really isn't possible to suggest that one leads to the other.

D. There could be an "aggressive gene" that makes parents more likely to spank and children more likely to bully. Having this gene in the family lineage could influence both spanking by the parents and bullying by the child.

5- Which of the following are confounding variables established in one of the statements in the previous question?Only include those for which confounding was actually described. (Multiple Answers).

A. Behavioral disorders such as ADHD

B. Size of child

C. Acting out or not

D. How they were raised

E. Agressivegene
