A retrospective descriptive study examined the duration of biologic use from veterans with rheumatoid arthritis (Tran et al., 2009). The values in Table 27-4 were extracted from a larger sample of veterans who had a history of biologic medication use (e.g., infliximab [Remicade], etanercept [Enbrel]). Table 27-4 contains simulated demographic data collected from 10 veterans who had stopped taking biologic medications. Age at study enrollment, duration of biologic use, race/ethnicity, gender (F = female), tobacco use (F = former use, C = current use, N = never used), primary diagnosis (3 = irritable bowel syndrome, 4 = psoriatic arthritis, 5 = rheumatoid arthritis, 6 = reactive arthritis), and type of biologic medication used were among the study variables examined.

1. What is the mean age of the sample data?

2. What percentage of patients never used tobacco?

3. What is the standard deviation for age?

4. What is the range of age values?

5. What percentage of patients were taking infliximab?
