Answer:
20
Explanation:
According to my research on the repeated measure design, I can say that based on the information provided within the question for this design they would need exactly 20 subjects. This can be said because the repeated measure design is a research method in which the same test subjects are used more than once for different treatments. Which in this case would be three different treatments, and since the scientists concluded they need the same amount of subjects for each treatment then they can use the same 20 subjects for all three treatments.

Explanation:
Based on kin selection Bob is most likely to help his brother Ralph.
Kin selection is a sub-theory of natural selection that states organisms tend to help those genetically related to them (relatives). In humans, this theory implies:
- The closest a person is in terms of genes, the most likely you are to help him/her.
- Helping relatives can sometimes decrease our chances to survive while increasing the survival chances of that person.
- We are less likely to help people that are not genetically related to us such as colleagues, friends, classmates, etc.
Based on this, Bob is most likely to help his brother rather than his step-sister, cousin, or best friend. This is because in terms of genetics Bob and his brother are very close.
