What was the average age in the Confirm I trial?

• A. 68.4
• B. 71.9
• C. 74.2
• D. 69.5

Answer: (B)

In this context, the main idea is understanding what the average age represents in a clinical trial. The average age (the mean) tells you the central point around which participants’ ages cluster and helps indicate who the study results will most apply to. It’s calculated by adding up everyone’s ages and dividing by the number of participants, so the decimal reflects the precise arithmetic from the full data. For the Confirm I trial, the mean age is 71.9 years. This means the total of all ages, when divided by how many participants there were, equals about 71.9. The value with one decimal places shows the exact computed average from the dataset, and it also matches the expectation that the trial population comprises mostly older adults, which is common in many conditions studied in such trials. Other numbers would suggest a different overall age distribution, which wouldn’t align with the reported demographic summary.
