Question

1. a scientist is investigating aging among lions in the wild. which of the following would you say is most interesting to them?

the mean age of lions in the sample
the mean age of lions in the population
the mean bodyweight of lions in the sample

Explanation:

The scientist's goal is to study aging in wild lions. A sample's mean age only describes the studied subset, while the population mean age describes the entire group of wild lions the scientist cares about, which directly addresses the research focus on aging in the wild lion population. Bodyweight is unrelated to the aging investigation.

Answer:

The mean age of lions in the population
