A plant with a height of 15 cm is added to the original data set, creating a new data set of the heights, rounded to the nearest centimeter, of 51 plants. Which statement best compares the mean and median of the new data set to the mean and median of the original data set?
The mean of the new data set is greater than the mean of the original data set, and the median of the new data set is greater than the median of the original data set.
The mean of the new data set is greater than the mean of the original data set, and the median of the new data set is equal to the median of the original data set.
The mean of the new data set is less than the mean of the original data set, and the median of the new data set is less than the median of the original data set.
The mean of the new data set is less than the mean of the original data set, and the median of the new data set is equal to the median of the original data set.
