Confidence Interval

Confidence in how close the sample mean is to the population mean
Depends on the sample size (𝑛) and standard deviation of the population (𝜎)
... 즉 표본크기와 모표준편차? 모집단의 표준편차,standard_deviation에 의존
If standard deviation of the population is unknown, will use the sample standard deviation $S$
Estimated standard error is $S/\sqrt{n}$ ... 표준오차,standard_error
