Question

People with chronic airflow obstruction are believed to have a limited exercise tolerance. This limited tolerance is thought to be mainly due to impaired ventilation mechanics. In a study designed to measure the effect (if any) that a new treatment had on the exercise capacities of individuals with chronic airflow obstruction, investigators measured, among other things, maximum exercise ventilation (VE_max) before and after the treatment was applied. The raw VE_max data are reproduced in the table below. The investigators would like to determine if there was an increase in the maximum exercise volume as a result of the treatment. Let ? = 0.025.

Baseline	20.6	18.8	20.7	20.1	21.2	22.7	22.3	22.9	19.0
After Treatment	21.9	20.9	20.9	21.3	22.8	27.1	23.3	18.7	25.4
Diff	1.3	2.1	0.2	1.2	1.6	4.4	1	-4.2	6.4
