Binomial distribution margin of error
WebThe z-score is the number of standard deviations a given proportion is away from the mean. To find the right z-score to use, refer to the table below: WebOct 15, 2010 · Hence, with a 5% margin of error, it means that n=400. While 2.2% means that n=2000: > 1/.022^2. [1] 2066.116. Classically, we compare proportions between two samples: surveys at two different dates, surveys in different regions, surveys paid by two different newpapers, etc. But here, we wish to compare proportions within the same sample.
