Breathing rates, in breaths per minute, were measured for a group of 5 subjects at rest, and the during moderate exercise. The results were as follows: 3 4 5 21 | 18 | 19 | 14 Exercised 30 39 40 | 34 34 Subject 1 2 Rest 15 Find a 90% confidence interval for the increase in breathing rate due to exercise. Interpret the interval in the context of the problem.
