May I know the solution to this?

Let X1, . . . , Xn be a random sample from an exponential distribution with the density f(a: | 6') = 6exp(0x). In Problem 55, we derived a likelihood ratio test of H0 2 0 : 00 versus H1 2 6 75 60, and found that the rejection region is of the form {X exp(00X') S c}. We deduced that the rejection region may be expressed in the form {X S :60} U {X 2 131}, Where 370 and $1 are determined by 0. Suppose, to be Specic, that 90 = 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
