3. (a) Suppose that ri,...,In are a random sample having probability density function C: a Here α is restricted to be positive. Determine the MLE of α (b) Suppose that ri, , Vn are a random sample from a geometric distribution ㄨㄧ Here the parameter 0 < θ < I. Determine the MLE of θ and show carefully that it is an MLE: it does not suffice to solve the score equation.
