Theoretical and Experimental Probability
... You can estimate the probability of an event by using data, or by experiment. For example, if a doctor states that an operation “has an 80% probability of success,” 80% is an estimate of probability based on similar case histories. Each repetition of an experiment is a trial. The sample space of an ...

We then used the sample standard deviations to estimate the population standard deviations. But what about when the two populations have the same standard deviation. This e ...
