2.9 In this question we consider maximum-likelihood estimation for the polyspermy example under the single Poisson process model. Suppose that we write the log-likelihood as:

l(λ) = C − λA + B(log λ)

for positive constants A, B and C. Obtain the value of λ that results in dl dλ = 0, and show that this corresponds to a maximum.
