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.
based on the data, which age group is most likely to use a navigation system?

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: $\frac{150}{500}=0.3$

Answer:

30 - 50
