Answer 1

Answer: D

Explanation:

The first data set, D1, has values ranging from 2.1 to 5.5, while the second data set, D2, has values ranging from 3.5 to 9.4. Since there is no overlap between the ranges of values in D1 and D2, these data sets show no overlap. In contrast, data sets A, B, and C all have overlapping ranges of values.
