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 percentage of drivers over 50 do not use a navigation system?

Explanation:

Step1: Identify the relevant numbers

The number of drivers over 50 who do not use navigation is 350. The total number of drivers over 50 is 500.

Step2: Calculate the percentage

Use the formula for percentage: \(\text{Percentage}=\frac{\text{Part}}{\text{Whole}}\times100\). Here, \(\text{Part} = 350\) and \(\text{Whole}=500\). So, \(\text{Percentage}=\frac{350}{500}\times100\).
