Answer 1

To find the marginal relative frequency for drivers, we need to divide the total number of drivers by the overall total and then convert that to a percentage.

From the table:

- Total number of drivers = 77
- Overall total = 119

Now, we calculate the marginal relative frequency for drivers:

\[
\text{Marginal relative frequency for drivers} = \frac{\text{Total number of drivers}}{\text{Overall total}} = \frac{77}{119}
\]

Now calculate the fraction:

\[
\frac{77}{119} \approx 0.6462
\]

To convert this to a percentage, we multiply by 100:

\[
0.6462 \times 100 \approx 64.62\%
\]

Rounding to the nearest whole percent gives us:

\[
65\%
\]

Thus, the marginal relative frequency for drivers is **65%**.
