Hello I need help solving this statistics problem that I cant figure out. Thank you for your help!

ace pg up se home 6 54 SIX 5 oscillates fas 1 . 0 = ( 2 ) 2 X. ( a) = 0 FX5 72 + enter In : y ky Let Yi,..., In denote a random sample from the density? given by m ( 2 ) 9 e 0 elsewhere where a zo is known. a ) what is the best ( minimal ) Sufficient statistic for O in this problem? From the likelihood function, lil is seen that U = 5 7, 1 is a sufficient statistic for 9. b ) Suppose that n=2 and d= 4 . Use the minimal sufficient statistic to construct a 20% confidence Interval for O. Eight : Transform to a x2 round your anover to four decimal places dist. ( chi- squand ))
