Let X1,…,Xn_1 and Y1,…,Yn_2 be random samples respectively from EXP(theta, eta_1) and EXP(theta, eta_2).(a) If eta_1, and eta_2 are known, construct a Most Powerful Test for testing H0 :theta = theta_1 against Ha : theta = theta_2 where theta_1 < theta_2 are given values at significance level alpha.
