Answer: alternative D.

Explanation: Dr. DeVries should choose his sample population randomly in order for his research to be representative, even having a specific population, which is high school seniors, that he wants to study. By <u>choosing specifically students from an exclusive college preparatory school, he isn't considering how students from other schools might perform in his research test</u>. This would be a very important step for him to understand how the practice in problem solving affects the ability related to it. Otherwise, he will have a distorted result.

const2013 [10]

The kind of person most people expect to find when they encounter someone with a babyish face is someone who is innocent, honest, weak, and less competent than other individuals with mature faces.

It has been demonstrated that the shape of the face directly affects the way people are perceived. As a result, a rounded (baby) face is much more likely to be perceived as naive, rather than a square face which shows toughness.
