Answer #1

Solution:-

Its Exponential Distribution and the random variable is iid.

Suppose tht,

X exp)

W want to test the

Ho: Verses  H1 = 2

f(x) = de lo

and Likelyhood Function is,

L= Пе-Аг 1=1

I=! PuP = 1

Threfore Likehood ratio is,

L1 LO 2e- n1 e-n-11-i

L1 LO 2e-Σ I;

Since,

TY Oy

Rejction rgion is,

I; <c

C VI n n

C k ,k>0(Fixd constant).

Therefore MP-test for testing Hypothesis,

Reject он if C k .
