An expectation-maximization (EM) likelihood estimation procedure is proposed for obtaining maximum likelihood estimates of parameters in a mixture distributions model with unknown mixture proportions based on type-I hybrid censored samples. Three bootstrap methods are utilized for constructing confidence intervals of the model parameters, and Monte Carlo simulations are conducted to evaluate the performance of the proposed methods. Simulation results demonstrate that the proposed methods can effectively provide reliable point and interval estimation results, with three examples illustrating their applications.
