To answer the question shown in the image, we need to identify the lower class limits based on the age intervals provided. Here’s how we approach the problem:

### Age Intervals Given:
- 21-30
- 31-40
- 41-50
- 51-60
- 61-70

### Step 1: Identify the Lower Class Limits
The lower class limit is the smallest value that can belong to each interval. So, for each interval:
- The lower class limit of 21-30 is **21**.
- The lower class limit of 31-40 is **31**.
- The lower class limit of 41-50 is **41**.
- The lower class limit of 51-60 is **51**.
- The lower class limit of 61-70 is **61**.

### Answer:
The lower class limits in ascending order are: **21, 31, 41, 51, 61**.

2. What is the class width for these intervals?
3. How would you calculate the class midpoint for each interval?
4. How do you determine the class boundaries if there were no gaps between intervals?
5. What is the total number of individuals based on the frequency given?

**Tip:** When working with frequency distributions, ensure that you clearly distinguish between class limits and class boundaries to avoid confusion in calculations.

Identify the lower class limits, upper class limits, class width, midpoints, and class boundaries for the given frequency distribution. Identify the number of individuals included in the summary.
