In this article, we partially solve a conjecture by Kochar and Korwar (1996)  in relation to the normalized spacings of the order statistics of a sample of independent exponential random variables with different scale
parameters. In the case of a sample of size n=3, they proved the ordering of the normalized spacings and conjectured that result holds for all n. We prove this conjecture for n=4 for both spacings and normalized spacings and generalize some results to n>4.
