In this study, we have launched a new two-parameter probability model called the New Lindley-Rayleigh distribution. The proposed model accommodates unimodal and bathtub, and a broad variety of monotone failure rates. Some statistical and mathematical properties of this distribution are discussed. Four widely used estimation methods are employed to estimate the model parameters namely maximum likelihood estimators (MLE), leastsquare (LSE) and Cramer-Von-Mises (CVM) methods. By using the maximum likelihood estimate we have constructed the asymptotic confidence interval for the model parameters. The potentiality of the proposed distribution is revealed by using a real dataset, where the proposed distribution provided better fit in comparison with some other lifetime distributions. The importance of the proposed distribution is illustrated by using a real dataset, and found that it provides a better fitting in comparison with other lifetime distributions.
