Chapter 11.2, Problem 28E

The paper “Less Air Pollution Leads to Rapid Reduction of Airway Inflammation and Improved Airway Function in Asthmatic Children” (Pediatrics [2009]: 1051–1058) describes a study in which children with mild asthma who live in a polluted urban environment were relocated to a less polluted rural environment for 7 days. Various measures of respiratory function were recorded first in the urban environment and then again after 7 days in the rural environment. The accompanying graphs show the urban and rural values for three of these measures: nasal eosinophils, exhaled FENO concentration, and peak expiratory flow (PEF). Urban and rural values for the same child are connected by a line.

The authors of the paper used paired t tests to determine that there was a significant difference in the urban and rural means for each of these three measures. One of these tests resulted in a P-value less than 0.001, one resulted in a P-value between 0.001 and 0.01, and one resulted in a P-value between 0.01 and 0.05.

Apply cd command to tell STATA the filepath associated with your "favorite folder" (use the same name for the favorite folder that we have been using in class) Apply log using command to tell stata that you are creating a log file to record the codes and the outcomes of these codes.
