# Two different computer systems are monitored for a total of n weeks. Let X i denote the number of breakdowns

## Question:

Two different computer systems are monitored for a total of n weeks. Let X_{i} denote the number of breakdowns of the first system during the ith week, and suppose the X_{i}’s are independent and drawn from a Poisson distribution with parameter μ_{1}. Similarly, let Yi denote the number of breakdowns of the second system during the ith week, and assume independence with each Y_{i} Poisson with parameter μ_{2}. Derive the mles of μ_{1}, μ_{2}, and μ_{1} – μ_{2}.
