Suggested answer to exercise: Comparing peak flow meters, 4

Question 4: Do you think the data meet the conditions for a paired t test?

Suggested answer

I think that the distribution of differences is approximately Normal and the differences are not related to the magnitude of the measurement, so I think that the data do meet the conditions of a paired t test.
