75.6% of drivers obey the law, given that they know the law.
From the provided table:
- Drivers who know the law and obey it = 155
- Total drivers who know the law = 205
To find the conditional relative frequency:
![\[\text{Conditional relative frequency} = \frac{\text{Drivers who know and obey the law}}{\text{Total drivers who know the law}} * 100\%\]](https://img.qammunity.org/2023/formulas/mathematics/college/w5abysvu36ndgjbe52wgsst7db042fnen0.png)
![\[\text{Conditional relative frequency} = (155)/(205) * 100\%\]](https://img.qammunity.org/2023/formulas/mathematics/college/wvlzjynlfaurg5cg15q9rifs2xpur0yzc3.png)
Calculating the fraction:
![\[\text{Conditional relative frequency} = (155)/(205) = 0.7561\]](https://img.qammunity.org/2023/formulas/mathematics/college/832oqq4uynd36jz6hhzyt1b2fekldxbdfm.png)
Converting to a percentage:
![\[\text{Conditional relative frequency} \approx 0.7561 * 100\% \approx 75.61\%\]](https://img.qammunity.org/2023/formulas/mathematics/college/rqaidqa0ctuqio9codzbjk21zuhwx5g30j.png)
Rounded to one decimal place, the conditional relative frequency is approximately 75.6%.
