What is an exit poll?
An election exit poll is a poll of voters taken immediately after they have exited the polling stations. Unlike an opinion poll, which asks whom the voter plans to vote for or some similar formulation, an exit poll asks whom the voter actually voted for. A similar poll conducted before actual voters have voted is called an entrance poll. Pollsters - usually private companies working for newspapers or broadcasters - conduct exit polls to gain an early indication as to how an election has turned out, since in many elections the actual result may take hours or even days to count. Typically a question that is asked is... "who did you vote for?"
Is accuracy a measure of how close an answer is to the actual or expected value?
Precision and accuracy are two ways that scientists think about error. Accuracy refers to how close a measurement is to the true or accepted value. Precision refers to how close measurements of the same item are to each other. Precision is independent of accuracy.
What is aceptable drawing accuracy standard?
The answer depends on the purpose. For example, the accuracy required from an engineering drawing is much greater than a child's drawing of his house.
It has to do with the accuracy and precision of a measurement procedure?
Reliability!
How is probability expressed?
as a fraction
The accuracy of a poll is usually expressed in terms of?
Population Error
The key factor in estimating the mathematical accuracy of an opinion poll is?
the answer is Whether the sample was selected from the population by a random method
What does accuracy of a DAC mean?
Deviation of real DAC output votlage from expected DAC output voltage for particular code written to the DAC. Accuracy is mostly expressed in LSB.
Why is density expressed in two significant figures?
Because density expressed in two significant figures depends on your accuracy of your measurements of mass and volume to calculate as well as any variables that you are expected to use.

Is a scientific poll official?
Who certifies the results of any poll? Generally it is the polling agency itself, through conducting spot checks on accuracy. No government agency oversees poll results, so there is nothing to make them "official," with the exception of election polls. Election polls are are not scientific polls, as they are not random samples of public opinion. Instead, everyone eligible to vote casts a ballot. Election polls are the only "official" polls.

32.110 has five significant figures, as the last 0 is unnecessary, but is included for accuracy. Expressed with four significant figures, it is 32.11
Why is the density expressed in two significant figures?
It is not always expressed in 2 sig figs. The number of sig figs depends on the accuracy of your measurements of mass and volume to calculate the density as well as any variables that you are expected to use the density with. There is no point in having a density expressed to 15 significant figures if then you are going to multiply it by volume expressed to 1 sig fig to determine the mass.
