Math Problem Statement
Solution
The question states that a survey of 1,141 adults found that 74% rated themselves as above-average drivers. The task is to calculate the actual number of respondents who rated themselves as above average.
Solution
- Total respondents = 1,141
- Percentage who rated themselves as above average = 74%
To find the number of respondents who rated themselves as above average, we calculate:
Since we are asked to round to the nearest whole number, the answer is:
Final Answer
The actual number of respondents who rated themselves as above average drivers is 844.

Here are five related questions to consider:
- What would be the number of respondents if only 60% rated themselves as above average?
- If the sample size increased to 2,000 with the same percentage, how many would rate themselves as above average?
- How would the answer change if the percentage increased to 80%?
- What is the percentage of respondents if 900 out of 1,141 rate themselves as above average?
- How could we calculate confidence intervals for the percentage of above-average drivers?
Tip: Always ensure you convert percentages to decimals before performing calculations!
