Jestion-4: (6 points) Suppose X1,X2, ...,Xn are independently drawn from a densit'g,r with pdf 2 3' f(:r)=%e-29; :r>-0,3>-0 .ere 6' is the unknown parameter. Suppose I90 is the true value(though unknown] of I? and E[X2] = 290 [3 points] For this particular problem, show that E[S(9|X1,X2, ...,X]3=90] = 0. [3 points] Calculate the Fisher information for this entire sample
