Confidence interval:
It is defined as the range which contains the value of true population parameter. The confidence interval is constructed for various population parameters like population mean, population standard deviation and so on.
The confidence interval can be interpreted as : With a stated level of confidence, it can be said that the true population parameter for which confidence interval is constructed lies with the obtained confidence interval.
