In this survey, we're looking to find out what percentage of people can swim, based on the given relative frequencies. Here’s a step-by-step breakdown:
1. Identify the Relative Frequencies:
- The survey results show two categories: adults and children, each with their relative frequency of knowing how to swim.
- Adults who can swim: 0.34
- Children who can swim: 0.48
2. Calculate the Total Relative Frequency of People Who Can Swim:
- To find out the total proportion of people who can swim, you should add the relative frequencies for both adults and children who can swim:
[tex]\[
0.34 + 0.48 = 0.82
\][/tex]
- This means 82% of the people surveyed (adults and children combined) can swim.
3. Convert to a Percentage:
- Since we are looking for a percentage, we interpret the relative frequency of 0.82 as 82%. This is because a relative frequency of 1 would equal 100%, so you multiply by 100 to get the percentage:
[tex]\[
0.82 \times 100 = 82\%
\][/tex]
Therefore, the percentage of people surveyed who can swim is 82%, which corresponds to option C.
