Table 6. Exposure to Soot ( g/m3)(n = 45) measured from school monitors predicting exposure to soot measured from personal monitors. Beta SE(Beta) P. Intercept 13.16 12.48 0.30. School outdoor soot ( g/m3) 0.48 0.13 <0.001. Exposure to ETS (yes/no) 5.72 1.80 <0.01. Exposure to gas cooking (yes/no) 2.55 1.76 0.16. TABLE 7. Association Between Exposure to Soot ( g/m3) and Selected Health Outcomes. Current Wheeze PR (95% CI)- 1.45(.80-2.61), Current Conjunctivitis PR (95% CI)- 2.18(1.13-4.21), Current Phlegm PR (95% CI)-2.24(1.27-3.93), Elevated Total IgE PR (95% CI)- 1.69(1.21-2.36). The data in table 7 represents soot exposure measured from monitors at different schools and four different health outcomes on children (n=2083) attending 24 schools in the Netherlands. Can we improve our school monitor estimate of the children's soot exposure if we have a sample of students (n=45; see Table 6) wearing personal monitors which are more accurate? What is the SE for current conjunctivitis used to calculate the C.I. in table 7
