office is less than the median number of patients

at Dr. Amine's office

D. The range of the data for Dr. Harris's office is less

than the range of the data for Dr. Amine's office

Answer 1

The data for Dr. Amine's office is more

symmetrical than the data for Dr. Harris's office.

Explanation:

Using visual inspection, Dr. Amine's office data is symmetrical as the median value is well. Positioned in between the box plot with approximately the same width to both left and right of the plot from the median value. While that of Dr. Harris office is clearly skewed.

From the median value and range values, Dr. Harris's office has greater value than Dr. Amine's office, hence the options are false. The interquartile range are also not the same.
