The number of events that occur are counted for 3 min. Twenty events occur the first minute, 16 events occur the second minute, and 21 events occur the third minute. Compare the likelihood with the maximum likelihood estimator of Λ with the likelihood if Λ = 20.0.
Find the likelihood as a function of the Poisson parameter Λ, find the maximum likelihood estimator, and evaluate the likelihood at the maximum and at the other given value of Λ.
