Answer: III only
Step-by-step explanation:
first, look at each statement
I is not true, because the range of Mrs. Dane's class is 6, while Mrs. Shepperd's is 7.
II is not true, because neither are symmetrical. Both are skewed to lower numbers (see how the majority of the data is in the low numbers? it's skewed)
III is true. Mrs. Dane's mode is just one higher than Mrs. Shepperd's
