1. The freshmen data is skewed right, while the sophomores data is roughly symmetric.
2. Yes, the freshmen have an outlier at 10 hours.
3. The sophomores data set has a greater center.
4. The freshmen group has a wider spread of data.
5. Sophomores may have more consistent homework expectations or spend more time on average due to course difficulty.
6. False
7. Tuesday’s data is skewed right; Saturday’s data is more symmetric and bell-shaped.
