QUESTION 6 In a study concerned with the possible effects of air pollution on the development of childhood asthma, the following data were obtained. A sample population of 2,400 children who lived in a city with high levels of air pollution was examined in January 2014. At the initial visit for the study, 200 children were found to have asthma and were excluded from further study. The asthma-free children in the study were followed for 6 years, and 450 new cases of asthma were diagnosed during that time. The children who were followed during the study contributed 11,190 years of person-time. Calculate the incidence rate of asthma per 100 population during this study. Round to the nearest whole number. Include only the numerical answer (no units) in the answer box.

In a study concerned with the possible effects of air pollution on the development of childhood asthma, the following data were obtained. A sample population of 2,400 children who lived in a city with high levels of air pollution was
examined in January 2014. At the initial visit for the study, 200 children were found to have asthma and were excluded from further study. The asthma-free children in the study were followed for 6 years, and 450 new cases of
asthma were diagnosed during that time. The children who were followed during the study contributed 11,190 years of person-time.
Calculate the incidence rate of asthma per 100 population during this study. Round to the nearest whole number. Include only the numerical answer (no units) in the answer box.
