"a contribution to statistics"
which of the following words best describes the authors view of humanity?
altruistic
optimistic
pessimistic
realistic

Referring to the "A Contribution to Statistics",I have concluded that the word Altruistic best describes the authors's  view of humanity,as the author,in the story reflects her care for the behavior of human populations and the way they act.
The word Altruistic means an act of unselfish and selfless. 
I hope this would be helpful.
