Does the equation represent a direct variation?
B. r. >-32
C.r < -2
D.r>-2
B) The first 100 students from an alphabetical list of sixth graders
C) One hundred random students from the entire school
D) One hundred random students from the sixth grade
One hundred randomstudents from the sixth grade. Therefore, option D is the correct answer.
In statistics, a simple random sample is a subset of individuals chosen from a larger set in which a subset of individuals are chosen randomly, all with the same probability. It is a process of selecting a sample in a random way.
First off, the survey should be focused on the sixth graders, since they are the demographic that will be voting for 6th grade treasurer.
Next, the group should be random, because random groups better represent the entire class than an alphabetic list. Maybe those first 100 kids in the list like Noah because he has a last name that begins with A or something. It's not likely, but it's something that could corrupt the data collection.
Therefore, option D is the correct answer.
