The dot plot shown represents the 15 values in data set A. For this data set, the values on the x-axis, from left to right, are 10, 11, 12, 13, and 14. Data set B is created by subtracting 5 from each of the values in data set A. Which of the following correctly compares the medians and the ranges of data sets A and B?

The median of data set B is equal to the median of data set A, and the range of data set B is equal to the range of data set A.
The median of data set B is less than the median of data set A, and the range of data set B is greater than the range of data set A.
The median of data set B is less than the median of data set A, and the range of data set B is equal to the range of data set A.
The median of data set B is greater than the median of data set A, and the range of data set B is less than the range of data set A.
