Question
A CBS News/New York Times opinion poll asked 1050 adults whether they would prefer
balancing the federal budget over cutting taxes; 602 of those asked said "Yes." The poll
was carried out by telephone, so people without phones are always excluded from the
sample.
Any errors in the final result due to excluding people without phones
are in addition to the announced margin of error.
O are included in the announced margin of error. 4
can be ignored, because these people are not part of the population.
O can be ignored, because this is a nonsampling error.
