To find the marginal relative frequency for drivers, we can use the total number of drivers and the overall total.
From the table:
- Total number of Drivers = 77
- Total number of individuals (both drivers and non-drivers) = 119
The formula for marginal relative frequency is:
\[ \text{Marginal Relative Frequency} = \frac{\text{Number of Drivers}}{\text{Total Number of Individuals}} \times 100 \]
Substituting the values:
\[ \text{Marginal Relative Frequency} = \frac{77}{119} \times 100 \approx 64.45% \]
Rounding to the nearest whole percent, the marginal relative frequency for drivers is 64%.
