Solution Steps

Step 1: Calculate the Actual Number of Respondents

To find the actual number of respondents who rated themselves as above average drivers, we use the formula:

\[ \text{Number of respondents} = \left( \frac{\text{Percentage}}{100} \right) \times \text{Total respondents} \]

Substituting the given values:

\[ \text{Number of respondents} = \left( \frac{84}{100} \right) \times 1131 = 0.84 \times 1131 = 950.04 \]

Rounding to the nearest whole number, we find:

\[ \text{Actual number of respondents} = 950 \]

Final Answer

The actual number of respondents who rated themselves as above average drivers is \\(\boxed{950}\\).
