Applications of Crack distribution can be applied in many areas, such as physics, engineering, biomedical and economics. The Crack distribution depends on three parameters. This distribution contains well known special cases as two-parameter distributions, Inverse Gaussian(IG), Length Biased Inverse Gaussian(LB), and Birnbaum-Saunders(BS). We will begin with the literatures study on the Inverse Gaussian, Length Biased Inverse Gaussian, and Birnbaum-Saunders distributions. In this paper, we will focus on the Bootstrap confidence intervals method for a population mean of Crack distribution.
