This lecture shows how to derive confidence intervals for the mean of a normal distribution. We tackle two different cases: when the variance of the distribution is known; when the variance is unknown. In each case we derive the level of confidence and we discuss how it is set. ...
Clearly, if you already knew the population mean, there would be no need for a confidence interval. However, to explain how confidence intervals are constructed, we are going to work backwards and begin by assuming characteristics of the population. Then we will show how sample data can be ...

In this study, we calculate confidence intervals for the mean of a normal data and a contaminated normal data. Some robust estimators against outliers are also considered to construct confidence intervals that are more resistant to outliers than the Student t confidence interval. The confidence ...
Confidence intervals demonstrate how sure researchers are that a mean will lie between two numbers. Identify the importance of point and interval estimates, confident levels and coefficients, and terms associated with confidence in statistics. Related...
This text transposes standard statistical estimators of the mean and its confidence intervals to the field of occupational noise exposure, assuming that the samples are independent and lognormally distributed. The hypothesis of lognormality is applied to the values of A-weighted sound exposure as defi...
