9.3 Fitting a Poisson Distribution: You count the number of times that the annoying "MacSweeper" popup window appears per hour when you surf the web. You wish to model these counts with a Poisson distribution. On day 1, you surf for 4 h, and see counts of 3, 1, 4, 2 (in hours 1 through 4 respectively). On day 2, you surf for 3 h, and observe counts of 2, 1,2. On day 3, you surf for 5 h, and observe counts of 3, 2, 2, 1, 4. On day 4, you surf for 6 h, but keep only the count for all 6 h, which is 13. You wish to model the intensity in counts per hour. (a) What is the maximum likelihood estimate of the intensity for each of days 1, 2, and 3 separately? (b) What is the maximum likelihood estimate of the intensity for day 4? (c) What is the maximum likelihood estimate of the intensity for all days taken together?

per hour when you surf the web. You wish to model these counts with a Poisson distribution. On day 1, you surf for 4 h, and

3, you surf for 5 h, and observe counts of 3, 2, 2, 1, 4. On day 4, you surf for 6h, but keep only the count for all 6 h, which is
13. You wish to model the intensity in counts per hour.
