In statistics, point estimation involves the use of sample data to calculate a single value (known as a statistic) which is to serve as a "best guess" or "best estimate" of an unknown (fixed or random) population parameter. More formally, it is the application of a point estimator to the data. In

A point estimate in a normal distribution may fall in the range of confidence interval or may fall outside the confidence interval. if it falls in the Null Hypothesis (inside the interval) we fail to reject the null hypothesis. if it falls on the alternate hypothesis. We will reject the null hypothe
