Quizplus · Accepted Answer

To find the number of people who are 30 years of age or older but less than 40 years of age, we need to add the frequencies of the age group 30-34, 35-39.

Frequency of age group 30-34 = 12
Frequency of age group 35-39 = 10

Total number of people in the age group 30 years of age or older but less than 40 years of age = 12 + 10 = 22. Therefore, the answer is C) 22. To find how many people are between 30 and 40 years old, we need to add up the frequencies of the 30-34, 35-39, and 40-44 age groups. The frequency of the 30-34 age group is 12, the frequency of the 35-39 age group is 10, and the frequency of the 40-44 age group is 0 (since we are not counting anyone over 40). Therefore, the total frequency of people between 30 and 40 years old is 12 + 10 + 0 = 22.
