Circle the answer.
A student says, "Cooler A is best because it kept ice the longest." Cooler A costs $30; the budget is $10. What is wrong with her claim?
- budgets do not matter in design
- Cooler A kept ice the shortest time
- keeping ice is not a criterion
- it ignores the cost constraint
Filter 1 uses sand and gravel. Filter 2 uses sand, gravel and charcoal. Filter 2's water smelled better. What can the class conclude?
- gravel alone fixed the smell
- sand made the water smell worse
- adding charcoal improved the smell
- both filters were exactly the same
Car A: 6 m, then 6 m, then 6 m. Car B: 9 m, then 2 m, then 7 m. Both averaged 6 m. Which is more reliable, and why?
- they are the same, because the averages match
- Car A, because its results stayed the same
- Car B, because its average is higher
- Car B, because it once went 9 m
Filter A: very clean water, costs $8. Filter B: clean water, costs $3. Both meet the "clean water" criterion. Budget: $5. Which is the best choice?
- neither, because both cost money
- Filter A, because it costs more
- Filter A, because it is the cleanest
- Filter B, because it is clean enough and within budget
