I think I should use 616 for the sample size, 3031 for population size, and 5% for percentage, but I am not sure. Using 616 as the sample size, result is +/- 1.54%. Using 34 as the sample size, result is +/- 7.29%. confidence-interval binomial-distribution survey ...

The lower limit and upper limit around our sample mean tells us the range of values our true population mean is likely to lie within. You typically see 95% confidence intervals reported but what does this mean?If we calculate a 95% confidence interval, we can be 95% confident that our in...
This is incorrect, though a separate method of statistical analysis exists to make such a determination. Doing so involves identifying the sample's mean and standard deviation and plotting these figures on abell curve. Confidence interval andconfidence levelare interrelated but are not exactly the sam...
Systematic samplingis a form of probability sampling. Similar to simple random sampling, it involves choosing random samples within a fixed periodic interval. Researchers calculate the interval by dividing the total population by the required sample size. ...
