A survey of 675 randomly sampled adults asked how many hours per week each respondent spent watching television. The margin of error was 3 hours per week. The confidence interval was taken at the 95% level. This means that, if the same survey question was repeated in 100 random samples of 675 adults, the results of about 95 of those surveys would be within 3 hours of the results of this survey.
