1. The freshmen's data is skewed right, while the sophomores' data is more symmetric and centered around 5-6 hours.
2. Yes, the freshmen have an outlier at 10 hours.
3. The sophomores have a greater center (median around 5.5) compared to the freshmen (median around 3).
4. The freshmen have a wider spread of data, ranging from 1 to 10 hours, while sophomores range from 2 to 8 hours.
5. Sophomores may have more consistent homework expectations or time management skills than freshmen.
6. False. The sophomores’ data is not uniform; it has a clear peak around 5-6 hours.
7. Tuesday’s data is skewed left with a gap in the 30s, while Saturday’s data is more evenly distributed across a wider age range.
8. Tuesday’s peak is in the 20s, while Saturday has multiple peaks across different age groups.
9. The center (median) for Tuesday is lower (around 23) than for Saturday (around 45).
10. Yes, the surveyor left out ages below 20 and above 65. This likely affected the data by excluding younger teens and older adults, skewing Tuesday’s data toward younger shoppers.
11. False. Saturday’s ages are not evenly distributed; there are clusters in the 20s, 30s, and 40s.
12. Tuesday’s data shape may reflect that fewer young adults or families shop on a weekday afternoon, resulting in a concentration of younger shoppers.
