66. Consider a random sample of size n from the shifted exponential distribution with pdf for x u and 0 otherwise (the graph is that of the ordinary exponential pdf with l  1 shifted so that it begins its descent at u rather than at 0). Let Y1 denote the smallest order statistic, and show that the likelihood ratio test of H0: u 1 versus Ha: u 1 rejects the null hypothesis if y1, the observed value of Y1, is  c.
