Question

I have a question to ask and its which is least valid way to simulate how many boys and girls are in a random sample of 20 students from a school population that is half boys and half girls? A flip a coin 20 x (time is x) assigning one outcome to boys and the other girls. B drop a coin all at once count the number of each outcome . C count how many boys and girls are in your math class of each and use a proportion. D have a calculator generate 20 random integers and count the number of even and odd integers.

Thank you to helps me.

Answer 1

The correct answer is: [C]:
___________________________________________________________
"count how many boys and girls are in your math class of each and use a proportion."
___________________________________________________________
Note: The question asks for the "least valid way" to simulate "how many boys and girls are in a "random sample" of "[20 students from a school population that is half boys and half girls".
___________________________________________________________
Among the answer choices given, this method would be the least consistent with—and least appropriate for—obtaining a "random sample".
This answer choice: [C] ; involves "precision" —and seems incomplete, as well.
