Results: Confidence intervals provide a method of stating the precision or closeness of the sample statistics. It contains lower and upper limits. Conclusion: We concluded that the hypothesis is very much useful and essential tool in medical, nursing, pharmacy and other science and biomedical sciences as well as in its research fields. Some numerical illustrations with suitable examples also there.
