1. Mode of the first set of numbers (a): 1
- The number 1 appears 10 times, which is more than any other number.
2. Mode of the second set of numbers (b): 3
- The number 3 appears 7 times, which is more than any other number.
3. Modal sport: Football
- Football has the highest tally with 11 votes.
4. Number of students in the class: 28
- Sum of all tallies: 4 (Rugby) + 11 (Football) + 10 (Hockey) + 3 (Cricket) = 28.
5. Number of more students who liked football than rugby: 7
- Difference in tallies: 11 (Football) - 4 (Rugby) = 7.
6. Dog with median age: Barney
- Ages: 1, 4, 7, 9, 12. Median is the middle value, which is 7 (Toto).
7. Dog with median weight: Lucky
- Weights: 8, 9, 14, 16, 30. Median is the middle value, which is 14 (Fido).
8. Median height: 1.80m
- Heights in order: 1.78m, 1.78m, 1.79m, 1.81m, 1.85m, 1.86m, 1.88m, 1.93m. Median is the average of the 4th and 5th values: (1.79m + 1.81m) / 2 = 1.80m.
9. Modal height: 1.78m
- The height 1.78m appears twice, which is more than any other height.
