Question

two - way table scenario
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 rates

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

Answer:

They have the highest usage of navigation systems.
