On the day before an election in a large city, each person in a random sample of 1,000 likely voters is asked which
candidate he or she plans to vote for. Of the people in the sample, 55 percent say they will vote for candidate
Taylor. A margin of error of 3 percentage points is calculated. Which of the following statements is appropriate?
(A)
The proportion of all likely voters who plan to vote for candidate Taylor must be the same as the proportion
of voters in the sample who plan to vote for candidate Taylor (55 percent), because the data were collected
from a random sample.
(B) The sample proportion minus the margin of error is greater than 0.50, which provides evidence that more
than half of all likely voters plan to vote for candidate Taylor.
(C)
It is not possible to draw any conclusion about the proportion of all likely voters who plan to vote for
candidate Taylor because the 1,000 likely voters in the sample represent only a small fraction of all likely
voters in a large city.
(D) It is not possible to draw any conclusion about the proportion of all likely voters who plan to vote for
candidate Taylor because this is not an experiment.
(E) It is not possible to draw any conclusion about the proportion of all likely voters who plan to vote for
candidate Taylor because this is a random sample and not a census.

After a series of gripping debates on campus, a political scientist claims that the proportion, p, of students at the college who say they're interested In their district's election results is now greater than 65%. A poll is commissioned, and 181 out of a random sample of 250 students at the college say they're interested in their district's election results. Is there enough evidence to support the political scientist's cdaim at the 0.10 level of significance? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.)

In order to test this, the manager asks 45 households in A and 49 households in B whether anyone in their household had used the theater last summer. 23 of the households surveyed in A responded "yes", and 35 of the households in B responded "yes".
