May I know the solution to this?

Let X1, . . . ,Xn be a random sample from an exponential distribution with the density f(:c | 0) : 0exp(9x). In Problem 55, we derived a likelihood ratio test of H0 : 9 = 60 versus H1 : 6 7 60, and found that the rejection region is of the form {X exp(00X) g c}. We deduced that the rejection region may be expressed in the form {X S 230} U {X 2 331}, where :60 and 231 are determined by C. Suppose, to be specic, that 00 = 1 and n = 10, and that the sample average X is found to be mobs. Find the pvalue (accurate to at least ve decimal places). Given x_obs=1.24
