Question
In Canada, bill C-16 passed with a vote of 248 in favour
(Yes), and 40 opposed (No). In other words, 86.1111% of
congresspersons voted Yes to bill C-16.
A week before the bill was passed, a journalist wants to
survey 36 congresspersons to determine the proportion of
congresspersons that will vote Yes. What is the probability
that the journalist's survey will give the exact same result
as the actual vote? In other words, if the journalist surveys
36 congresspersons, what is the probability that 86.1111%
of those surveyed will be voting Yes?
0.189 x
Hint: You will need to determine what 86.1111% of the 36
is..this will tell you how many Yes's the journalist is looking
for...
What is the probability that the journalist is within 5% of
the actual proportion (86.1111%) of Yes voters?
0.7761 ×
Hint: You want the number of Yes voters to be within
86.1111% - 5% and 86.1111% + 5% of 36. What are the
possible number of Yes voters that fall within this range?
