Table 1. Distribution of Respondents According to Age Ages 18–24 25–29 30–39 40–49 50–64 65 or older
Percentage 9% 7% 16% 16% 30% 22%
Answer these questions about the chart described above:
Interpret the first column entries. How many respondents were 18–24 years old when the survey was taken?
How many respondents were 50–64 years old when the survey was taken? If 1,000 more voters were surveyed, how many would have been added to this group?
What age-group had the lowest number of respondents when the survey was taken?
What age-group had the greatest number of respondents when the survey was taken?
When combined, the total number of respondents from these two groups will be equal to the number of respondents in the age-group 40–49 years. What are these two age-groups?
How many more respondents belong to the group 18–24 than in the group 25–29 years? If 1,000 more voters were surveyed, how many more would have been added to the age-group 18–24 years than to the group 25–29 years?
- The first column entries show the percentage of respondents in each age category.
- There were 9% of respondents who were 18-24 years old when the survey was taken. If 1,000 more voters were surveyed, 90 more respondents would have been added to this age group.
- The age group with the lowest number of respondents when the survey was taken was the 25-29 age group with 7%.
- The age group with the greatest number of respondents when the survey was taken was the 50-64 age group with 30%.
- When combined, the total number of respondents from the 30-39 age group and the 65 or older age group will be equal to the number of respondents in the 40-49 age group.
- There are 2% more respondents in the 18-24 age group than in the 25-29 age group. If 1,000 more voters were surveyed, 20 more would have been added to the 18-24 age group compared to the 25-29 age group.
