To test this claim, a researcher obtains a sample of n = 16 adults who claim to be happy people and a similar sample of n = 16 adults who describe themselves as neutral or unhappy. Each individual is then asked to identify the number of their close friends whom they consider to be happy people. The scores are as follows:
