Question

Heidi is doing a study for her statistics class, and she needs to obtain a random sample of students from a local college. [The enrollment at the college is summarized in the table shown.]

Choose the BEST way to obtain a sample of size 50

Answer 1

Since you didn't get the choices, I can only give you some direction in selecting your answer.

For the best sample, you want to find a sample that is truly random. Calling names from a directory would be a good example of something random. Selecting random student numbers from a list would be a good idea.

You want to avoid samples that aren't random. For example, don't survey everyone in a particular class. You may get a biased result in favor of that type of class.

Answer 2

the answer is (C) i hope this works for you  but before you click make sure its the answer that the sample is actually random because usatestprep be switching sometimes.
