Question

in a poll of 1100 registered voters before a mayoral election, 594 people (54%) said they would vote for the current mayor. the margin of error was ±3%, which means the poll predicts that between 51% (54 - 3) and 57% (51+3) of people will actually vote for the sitting mayor. which does the poll represent? an experiment schrodinger’s cat a sample survey an observational survey

Explanation:

A sample survey involves gathering data from a subset (sample) of a larger population to make inferences about the whole population. Here, 1100 registered voters are surveyed to predict the voting behavior of all voters in the mayoral - election, which fits the definition of a sample survey. An experiment involves manipulating variables, which is not the case here. Schrodinger's cat is a thought - experiment in quantum mechanics and is not relevant. An observational survey just observes without sampling, which is also not applicable as a sample of 1100 voters is taken.

Answer:

C. A sample survey
