**MEDAL** Which of these is an example of a random sample? A.Henry asks five of his friends to fill out a survey to find out their favorite musicians. B.The five people seated on the first row at the circus are asked their opinion about the animal acts. C.The five employees who work the late shift answer questions about management. D.Five employees out of 2,000 are chosen randomly to complete an anonymous survey.

OpenStudy (hysusonic):

okay so random sample means that it isn't a specific group of people (and please ignore those trolls)

OpenStudy (hysusonic):

@morgobeby okay so since it isn't a specific group, which ones can we eliminate?

OpenStudy (hysusonic):

hello?

OpenStudy (anonymous):

ummm d?

OpenStudy (anonymous):

@hysusonic

sammixboo (sammixboo):

Do you think it is or isn't D?

OpenStudy (anonymous):

isnt

sammixboo (sammixboo):

Look at all the choices. The choices that are choosing from a specific group of people is not a random selection while choosing randomly so and so people from blah blah. Get what I am saying? Trying to put this in a good way

OpenStudy (anonymous):

so i am or not looking for a random selection?

sammixboo (sammixboo):

You ARE loooking for a random selection

OpenStudy (hysusonic):

sorry i was helping someone else xDDD okay if you look at A, is he going up to random people or specific people?

OpenStudy (anonymous):

specific ^

OpenStudy (hysusonic):

okay so you can cross that one off and how about answer choice B?

OpenStudy (anonymous):

random

OpenStudy (hysusonic):

why would it be random?

OpenStudy (anonymous):

because its random people at a circus right?

OpenStudy (acxbox22):

well specifically isnt it ONLY the FIRST row?

OpenStudy (anonymous):

yes..

OpenStudy (acxbox22):

so u can eliminate that too..

OpenStudy (hysusonic):

well that is true but it's saying specifically the first 5 people in the first row so it can't be random

OpenStudy (anonymous):

alright..

OpenStudy (hysusonic):

okay so now we move onto C, is that specific or random?

OpenStudy (anonymous):

ahhhhh i see, C is specific thou.

OpenStudy (hysusonic):

yup because it's only interviewing the people working the night shift so you're left with D

OpenStudy (anonymous):

:') lol, basically the answer was right there. Thank youuuuu

OpenStudy (hysusonic):

OpenStudy (anonymous):

OpenStudy (hysusonic):
