'''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_deviation]]에 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]]
