Using Output 2, prepare a table including some basic summaries of the categorical variables in the data set. Table 13: General characteristics of the study population [categorical variables} Summary (n=654) Number (96) Current Smoker Yes 65 (9.9%) Current Smoker No Female Q3. Imagine you are preparing your data analysis for a written publication. Using your completed Tables 1A and 13, write 2-3 complete sentences highlighting some of the key features of the study population.

Example: The study population includes 654 children ranging in age from 3 to 19 years (mean age 9.9 years)... Summary (n= 654) Mean + SD (Min, Max) Age (Years) 9.93 12.95 (3, 19) Height (Inches) 61.14 + 5.70 (46, 74) FEV (Liters) 2.64 + 0.87 (0.79, 5.79)
