To determine the joint relative frequency of those in Town 2 who take a summer vacation, we follow these steps:
1. Identify the number of residents in Town 2 who take a summer vacation:
According to the given data, 345 residents of Town 2 take a summer vacation.
2. Determine the total population across all towns:
The total population is given as 1,402.
3. Calculate the joint relative frequency:
The joint relative frequency is found by dividing the number of residents in Town 2 who take a summer vacation by the total population, and then multiplying by 100 to get a percentage.
[tex]\[
\text{Joint Relative Frequency} = \left( \frac{\text{Number of Town 2 residents taking a summer vacation}}{\text{Total Population}} \right) \times 100
\][/tex]
[tex]\[
\text{Joint Relative Frequency} = \left( \frac{345}{1402} \right) \times 100
\][/tex]
This yields a joint relative frequency of approximately 24.61%.
4. Round the joint relative frequency to the nearest whole number:
Rounding 24.61% to the nearest whole number gives us 25%.
Therefore, the joint relative frequency of those in Town 2 who take a summer vacation, rounded to the nearest percent, is 25%.
