The data is successive measurements of blood pressure.
Is it sample or population st deviation?

We have always used sample unless it specified that the whole population was used, we can assume that only a sample of the data based on his blood pressure was used and not all of the data.

Question asks what 'this person's mean and standard deviation' is, so it should be sample shouldn't it?
