To find the median, you first need to sort the numbers in ascending order and then determine the middle value. First set: Sorting \( 17, 19, 32, 10, 22, 21, 9, 35 \) gives \( 9, 10, 17, 19, 21, 22, 32, 35 \). With 8 numbers (even), median is the average of the 4th and 5th values: \( (19 + 21) / 2 = 20 \). Second set: Sorting \( 72, 63, 29, 51, 35, 60, 55, 91, 85, 82 \) gives \( 29, 35, 51, 55, 60, 63, 72, 82, 85, 91 \). With 10 numbers (even), median is \( (60 + 63) / 2 = 61.5 \). Third set: Sorting \( 10, 75, 3, 15, 9, 47, 12, 48, 4, 81, 17 \) gives \( 3, 4, 9, 10, 12, 15, 17, 47, 48, 75, 81 \). With 11 numbers (odd), the median is the 6th value, which is \( 15 \). So, the medians are: (i) 20, (ii) 61.5, (iii) 15.
