The question is asking whether the samples are independent or dependent based on a dataset of morning and evening temperatures over the last 200 days.

In this case, morning and evening temperatures for each day are naturally paired because they are measurements from the same day. This creates a dependent relationship. Therefore, the correct answer is:

A. The samples are dependent because there is a natural pairing between the two samples.

Tip: In paired samples, each data point in one sample is uniquely related to a data point in the other sample (e.g., pre-test and post-test scores of the same group).
