You get why right?

Answer 17

does the whole population LISTEN to the radio?

if so
does the whole population have time ot respond to the advert?

if so does the first nine make a reasonably 'random' sample - maybe the advert was broadcast at 5 a.m. - is everyone awake and ready to phone in at that time?

does the sample therefore represent the whole population?

Answer 18

no but that is not the question peace out

Answer 19

dude you have to make a new question you cant do that lol

Answer 20

@GreatGuy
how do you 'know it is valid'?

you are not correct

Answer 26

you have missed the point.

it doesn't ask if the responders are unbiased
it asks if they are a valid RANDOM sample of the WHOLE population

see my questions above.

this is not a valid sample

Answer 28

Answer 30

does the whole population LISTEN to the radio?

answer NO

therefore a sample drawn from ONLY radio listeners cannot be a representative sample of the population

Answer 31

i still don't get what the answer is...

Answer 32

look it is a good sample because it is random so it is a or d

Answer 33

that's because you are waiting for someone to give you the answer

(it seems the other current posters do not really know so I suggest you ignore them)

try looking at my questions in earlier post and thinking about what you have been told about random samples.

Answer 34

@shinebrightlikeadimon
it is not a random sample - I suggest you stop posting on a topic you clearly do not understand

Answer 35

does the whole population LISTEN to the radio?

if so
does the whole population have time ot respond to the advert?

if so does the first nine make a reasonably 'random' sample - maybe the advert was broadcast at 5 a.m. - is everyone awake and ready to phone in at that time?

does the sample therefore represent the whole population?
