![4. Probability maximization: We have independent random variables X and Y with distribution X~
Poisson (p) and Y~ Poisson (20), and observations x = 2 and y = 5 of these.
(a) Show that the expression for the log-likelihood function is given by:
ι(φ)
[5 ln (2) In (2!)
In (5!)] + 7 ln p – 30.
Plot 1() for values of € [0,10] (a rough sketch is OK). For what value of p does l() have its
maximum?
