After the blood samples were analyzed, the results might look like this: 57. Other terms that can be used to describe the concept are arithmetic mean, average and mathematical expectation. Remember to always try to disprove a hypothesis, not prove it. Rather, it reflects the amount of random error in the sample and provides a range of values that are likely to include the unknown parameter. This last expression, then, provides the 95% confidence interval for the population mean, and this can also be expressed as: Thus, the margin of error is 1.
