2. An experiment is set up to test the effectiveness of a new drug for balancing
people's mood. The table below contains the results of the patients before and
after taking the drug. The possible scores are the integers from 0 to 10, where
0 indicates a depressed mood and 10 indicates and elated mood.

The number of claims is modelled by a NB2(n, p) (the number of fail-
ures before the nth success with probability p of success). The sample x =
