A behavioral economist has conducted an experiment in which she compares offers in the dictator game and the ultimatum game. She had a very small budget and could only gather three independent observations with each game. Her design is one-shot and across-subjects. She observes the following offers.

Ultimatum game: 30, 35, 50

Dictator game: 0, 12, 33

Can she reject the null hypothesis of no treatment difference at the one-sided 5% level, using Fisher's two-sample randomisation test?
