#ConfidenceInterval #ConfidenceIntervalMean #ConfidenceIntervalExpectedValue #UnknownVariance How do you calculate the confidence interval for an unknown expected value? I'll show you how to determine the confidence interval for the mean (confidence interval with unknown variance). We calculate the 95% confidence interval and the 99% CI. I'll show you the difference between T-quantile and Z-quantile and how to read the Z-value or T-value from the table or when to choose the T-distribution or normal distribution. I'll also explain how to interpret the confidence interval or confidence interval. ☕ Buy a coffee: https://bit.ly/Kaffeespende-Statistik... ????
