The sample size is a statistic that is used in the calculation of confidence interval. The sample size for proportion is calculated by the given formula: Sample size=(Zα/2)2×p(1−p)ε2where ε is margin of error The sample size is denoted by n...
In computing the sample size needed in a 95% confidence interval, is the margin of error the same as the sampling error? How to find the margin of error in StatCrunch? find the margin of error: 95% confidence interval; n = 51, x-bar = 129; s = 274 ...

The 95% is the confidence level and the +/-3 is called a margin of error. The article reported, “For the European data, one can say with 95% confidence that the true population for wellbeing among those without TVs is between 4.88 and 5.26.” The confidence interval here is “between...
i can only guess that the names of your tables are different. In my file and in the code (posted above) the names of the tables are "Tabelle1" und "Tabelle2". Perhaps you can attach your file without sensitive data. This would be very helpful to find the re...

Younger voters in Arizona break narrowly in Trump’s favor: 48% of likely voters younger than 35 say they support Trump, compared with 42% behind Harris, a result within the margin of sampling error for that subset. In Nevada, though, likely voters in that age group divide 54% to Harri...
Let me warn you: The sample size formula can be a little overwhelming. But we'll work through it together. Why Confidence Levels and Margin of Error Matter There are some key terms you want to know before getting to sample sizes. These include confidence levels and margin ...

If n = 25, x bar = 33 and s = 9, find the margin of error at an 80% confidence level. Give your answer to two decimal places. In computing the sample size needed in a 95% confidence interval, is the margin of error the same as the sampling error?
