Correlation and causation

Full solution

Q. Each of these relationships reflects a correlation. Which relationship most likely reflects correlation but not causation?

\newline

Choices:

\newline

(A) Washing laundry more often is associated with using more water.

\newline

(B) Dusting the furniture more often is associated with having shinier furniture.

\newline

(C) Vacuuming living room carpets more often is associated with having cleaner bathrooms.

Analyzing Relationship of Option A: Analyze the relationship of the first option ( extit{A}): Does washing laundry more often cause an increase in water usage? The answer is Yes, as using more water is a direct consequence of washing laundry more often. This suggests a causation, not just correlation.
Analyzing Relationship of Option B: Analyze the relationship of the second option (B): Does dusting the furniture more often cause the furniture to be shinier? The answer is Yes, as the act of dusting is intended to clean and thus enhance the shine of furniture. This also suggests a causation, not just correlation.
Analyzing Relationship of Option C: Analyze the relationship of the third option ( extit{C}): Does vacuuming living room carpets more often cause having cleaner bathrooms? The answer is No, as the cleanliness of bathrooms is independent of how often the living room carpets are vacuumed. This suggests a correlation that is likely not due to causation.
Selecting Likely Correlation: Finally, select the option that most likely reflects correlation but not causation. The answer is 'Vacuuming living room carpets more often is associated with having cleaner bathrooms.' as the two activities are not causally related.

A large truck, traveling

30

miles per hour, carries a letter from the central post office to the local post office. The letter is then loaded onto a local vehicle, which travels at an average speed of

10

miles per hour, until the letter reaches its destination. The large truck carried the letter for

a

minutes and the local vehicle carried the letter for

b

minutes. If the total distance that the letter travelled from the central post office to its destination was

24

miles, which of the following equations correctly relates

a

b

\newline

\newline

\frac{30}{60} a+\frac{10}{60} b=24

\newline

\frac{60}{30} a+\frac{60}{10} b=24

30 a+10 b=24

\newline

60 \cdot 30 a+60 \cdot 10 b=24
