$$R_1$$: 13.2, 14.2, 15.2, 16.2, 17.2
$$R_2$$: (13)(0.2), (14)(0.2), (15)(0.2), (16)(0.2), (17)(0.2)
$$R_3: \frac{13}{0.2}, \frac{14}{0.2}, \frac{15}{0.2}, \frac{16}{0.2}, \frac{17}{0.2}$$
If $$s_1, s_2$$,and $$s_3$$ are the standard deviations of lists $$R_1, R_2$$,and $$R_3$$ respectively,which of the following shows the standard deviations in order from least to greatest?
