Question

Imagine an experiment wherein participants were told of a previously unknown tribe living on a Pacific island. Only one member of this tribe had been observed so far, and he was found to be obese. When asked how likely it was that all members of the tribe were obese, participants were unwilling to extrapolate this information. This shows that participants

a.
were using the representative heuristic.
b.
had prior beliefs about these islanders.
c.
are sometimes sensitive to the sample size and can take this into account when making a judgment.
d.
are unwilling to make a judgment, as they are wary of making an error.

Answer 1

are sometimes sensitive to the sample size and can take this into account when making a judgement

Step-by-step explanation:

The sample size here is really small and as such is insufficient for the exercise/ experiment. Participants were unable or rather unwilling to answer the question or make extrapolation on the obesity of the tribe given the sample size insufficiency. This therefore shows participants are considering sample size in making judgements or extrapolation on the tribe here
