Abstract

When the sample is small (n <30) and assumed that the population is not normally distributed, not the normal distribution or the Student t-distribution can be used in the construction of a confidence interval. In this case, we use the Chebyshev inequality. Statistical analysis of survival, the time variable is not normally distributed. The objective of this study was to use the Chebyshev inequality in the bootstrap method to estimate confidence intervals for analysis of survival time. To this end, we constructed a computer program in C ++ in order to form the bootstrap distribution and calculate the average survival times. The results showed that the Chebyshev inequality when used in conjunction with the bootstrap method consisted in an excellent statistical tool for estimating the range of survival time.
