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 (VEmax) before and after the treatment was applied. The raw VEmax 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.

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 (VEmax) before and after the treatment was applied. The raw VEmax 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.
