Answer:
0.1 is the outlier
Explanation:
Though the question has a missing attachment (of the line plot), the question can still be answered.
The given data can be represented as;
![\begin{array}{cc}{} &{Dots} & {0.1} & {1} & {0.5} & {2} & {0.6} & {4} & {0.7} & {1} \ \end{array}](https://img.qammunity.org/2022/formulas/mathematics/high-school/u2waxvzvck13nqbuy86d4jpeizv3e5o3ix.png)
Notice that 0.1 is not as close as to other data as the closeness of 0.5, 0.6 and 0.7.
This implies that 0.1 is an outlier.
