Quizplus · Accepted Answer

To find the median, we need to arrange the data values in ascending order: 11, aa, 4a, e7, b2, e8, 91, 80, df, cd, 1f, 00, TB, 23, 39, 00. Since there are 16 data values, the median is the average of the 8th and 9th values. These values are 80 and df, which are hexadecimal numbers. Converting them to decimal gives 128 and 223, respectively. So, the median is (128 + 223)/2 = 175.5, which rounded to the nearest integer is 176. However, none of the answer choices are 176. The closest choice is B, 14, which is a common mistake made by those who don't convert the hexadecimal values to decimal.
