Question:

10.34 Vital capacity One of the authors of this book has his lung function checked every other year. At each checkup, his lung volume (called the forced vital capacity, or FVC)

is measured before and after using an inhaler that contains medication against asthma. The last five checkups provided the following results (in liters):

Checkup 1 2 3 4 5 Before using inhaler: 5.08 5.99 5.32 6.03 5.44 After using inhaler: 5.36 5.98 5.62 6.26 5.68 Can we use the inferential methods (confidence interval, significance test) developed in this section to compare the mean FVC before and after using the inhaler? If yes, use software to find a 95% confidence interval for the difference in the population means before and after using the inhaler and interpret it. If no, explain why.
