Final Answer : D, Explanation :  First, arrange the data in ascending order: 9, 10, 12, 14, 15, 16, 17, 18. The median of an even number of values is the average of the two middle numbers, which are 14 and 15, so the median is (14+15)/2 = 14.5. The mean is the sum of all values divided by the number of values, which is (9+10+12+14+15+16+17+18)/8 = 111/8 = 13.875, rounded to 13.88.

For the set of data, the median is and the mean is . 15, 10, 18, 9, 12, 16, 14, 17

A) 14.50; 111.00
