发帖数: 2 | 1 In a series of mine 108 explosions in England, the time interval between
the first and 54th accidents
was 8,042 days, whereas the interval between the 55th and 108th accidents
was 16,864 days. If it is
assumed that mine explosions followed a Poisson process in each period, and
that they did so at constant
rates λ1 and λ2 respectively, set up and carry out a test of the
hypothesis λ1=λ2 based on an F-statistic.
这个假设检验怎么建立咧？？？？ | s********e

You may find this article helps. I am not sure.
