Question

ng and safety data
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.

age group	uses navigation (yes)	does not use navigation (no)	total
30–50	400	100	500
over 50	150	350	500
total	750	750	1,500

what can be inferred about the behavior of younger drivers (under 30) toward navigation system usage?

• their behavior is inconsistent.
• they use navigation systems more than older drivers.
• they have the highest usage of navigation systems.
• they prefer not to use navigation systems.

Explanation:

For drivers under 30, the number of those who do not use navigation (300) is greater than those who do (200). Comparing to 30 - 50 (400 use, 100 don't) and over 50 (150 use, 350 don't), under 30 has a higher non - usage count relative to usage, indicating a preference not to use navigation systems. The option "Their behavior is inconsistent" is not supported as the data shows a clear trend. "They use navigation systems more than older drivers" is wrong as over 50 has lower usage but under 30 also has lower usage than 30 - 50. "They have the highest usage of navigation systems" is wrong as 30 - 50 has higher usage.

Answer:

They prefer not to use navigation systems.
