Question

the table categorizes drivers into age groups (under 30, 30 - 50, over 50) and whether they regularly use a navigation system (yes, no). data in the table is based on a fictional dataset.
what can be inferred about the behavior of younger drivers (under 30) toward navigation system usage?
they use navigation systems more than older drivers.
they have the highest usage of navigation systems.
they prefer not to use navigation systems.
their behavior is inconsistent.

Explanation:

Step1: Calculate usage rate for each age group

For under - 30: $\frac{200}{500}=0.4$
For 30 - 50: $\frac{400}{500}=0.8$
For over 50: $\frac{150}{500}=0.3$

Step2: Analyze the results

Younger drivers (under 30) have a usage rate of $0.4$, which is lower than the 30 - 50 age group's $0.8$ but higher than the over 50 group's $0.3$.

Answer:

They use navigation systems more than older drivers.
