Here we have proposed a new distribution by applying the technique of transformation, length biased to the parent distribution. The new distribution is termed Length Biased Modified Aradhana distribution (LBMAD) has been presented. Also detailed the important statistical properties like moments, survival function, hazard function, and moment generating function. Also, the approach of maximum likelihood estimation was used to figure out the parameters of the new distribution. Lastly, a set of real-time data has been shown and analyzed to show how useful a new distribution is. A randomly selected 180 patients from a hospital at Chennai, which shows the mean reduction (mg/dL) of low-density lipoproteins (LDL) from the Near Optimal range of LDL(100 – 129) after taking the prescribed diet and physical exercise as prescribed by their consultant dietician for four weeks continuously
