LetX1, . X, be a random sample from an exponential distribution with the. density f(x.| 0) = 0.exp(-Ox)..

X be a random samplefrom an exponentialdistribution with the Let Xl' n We havederived likelihood ratiotest of Hog versus HI * 90, andfound that the rejectionregionis oftheform {R exp (90k) c}. We deduced that the rejection region maybe expressedin theform {R xo} 2 Xl}, where xo and Xl aredetermined by c. Suppose.tobe specific, 1 and and that the sample average R is foundtobe0.72.Find the p-value(accurateto atleastfivedecimal places).
