• A majority of the departments that have more research labs than the university-wide average also have a student age above the university-wide average.
Average labs = 5.7. Departments with more labs: Biology (6), Engineering (10), Physics (7), Economics (6), Computer Science (9). Their ages: 27.9, 45.5, 33.7, 38.9, 52.3. Three of these (Engineering, Economics, Computer Science) are above 37.2, the overall average. That is 3 out of 5, a majority.
Answer: True
• The range of student ages among departments with evening classes is greater than the range of student ages among departments without evening classes.
Departments with evening classes: Biology (27.9), Engineering (45.5), Physics (33.7), Economics (38.9), Sociology (36.5), Computer Science (52.3). Range = 52.3 − 27.9 = 24.4.
Departments without evening classes: History (34.2), Mathematics (31.6), Literature (41.8), Philosophy (29.4). Range = 41.8 − 29.4 = 12.4.
Since 24.4 > 12.4, the statement holds.
Answer: True
• Every department that has both library access and international programs also has an above-average student age.
Departments with both library access and international programs: Literature (41.8), Philosophy (29.4), Computer Science (52.3). Literature and Computer Science are above 37.2, but Philosophy is below. Because not all qualify, the condition fails.
Answer: False
