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) Riding a bicycle more often is associated with stronger leg muscles.

\newline

(B) Riding a bicycle more often is associated with hiking more often.

\newline

(C) Riding a bicycle more often is associated with wearing a helmet more often.

Analyze Relationship of Option (A): Analyze the relationship of option (A): Does riding a bicycle more often cause stronger leg muscles? The answer could be Yes, as stronger leg muscles could be a result of the physical exercise that comes with riding a bicycle.
Analyze Relationship of Option (B): Analyze the relationship of option (B): Does riding a bicycle more often cause someone to hike more often? The answer is not necessarily, as these are two different activities that don't cause each other, but people who enjoy outdoor activities might tend to do both.
Analyze Relationship of Option (C): Analyze the relationship of option (C): Does riding a bicycle more often cause someone to wear a helmet more often? The answer is Yes, as wearing a helmet is a safety measure that is likely to be taken by someone who rides a bicycle frequently.
Select Most Likely Option: Finally, select the option that most likely reflects correlation but not causation. The answer is 'Riding a bicycle more often is associated with hiking more often.' as the two activities are correlated due to similar interests in outdoor activities but one does not cause the other.

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

1

\newline

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

\newline

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

\newline

30 a+10 b=24

\newline

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