Question

Davina selected 50 people at random and asked them whether they had watched the documentary on Antarctica on television the previous night. She repeated this survey using the same method three more times.

Do any of the surveys appear to be biased?

Watched Antarctica documentary last night? Survey
1 2 3 4
Yes 13 14 35 17
No 37 36 15 33


A.
Yes, because all four surveys do not have identical results.

B.
Yes, because the results from Survey 3 differ significantly from the other surveys’ results.

C.
No, because Davina surveyed the same number of people

Answer 1

C makes the most sense because she surveyed 50 people each time (not 100%sure tho)

Answer 2

It is a multi answer question. there is on more answer

Answer 3

is there only 3 options A, B, and C?

Answer 4

?

Answer 5

oooooohhhhh i see
one sec

Answer 6

Here is the last answer
D.
No, because all four surveys have about the same number of people saying “yes” and about the same number of people saying “no.”

Answer 7

What do you think it is?

Answer 8

I'm THINKING its C and D only because
like i said with c each time it was only 50 people
and for D it for "yes" it all apprears to be in the teens besides survey #3 and for "no" it on the 30s besides #3


so i think its c and d
