Answer:
[tex]R=8[/tex]Explanation: We have to find the data range for the provided data set, the data range is the spread of the data from the lowest to the highest, for the given data set the range would be as follows:
[tex]R=V_H-V_L[/tex]Therefore the range is:
[tex]\begin{gathered} S=4,2,6,6,1,3,9,5,7\rightarrow1,2,3,4,5,6,6,7,9 \\ \\ \\ S=1,2,3,4,5,6,6,7,9 \\ \\ \\ R=V_{H}-V_{L} \\ \\ \therefore\rightarrow \\ \\ R=9-1=8 \\ \\ \\ R=8\rightarrow(1) \end{gathered}[/tex]Therefore (1) is the answer.
