Questions: Identify the lower class limits, upper class limits, class width, class midpoints, and class boundaries for the given frequency distribution. Also identify the Age (yr) when 10-14, 15-19, 20-24, 25-29, 30-34, 35-39, 40-44. Frequency: 3, 34, 12, 3, 6, 2, 2, 3. Identify the lower class limits.

Solution Steps

To identify the lower class limits of a frequency distribution, we need to look at the starting value of each class interval. The lower class limit is the smallest value that can belong to a class. For the given frequency distribution, we will extract the starting value of each age range.

To find the lower class limits of the given frequency distribution, we examine the starting value of each class interval. The lower class limit is the smallest value that can belong to a class. For the class intervals provided, these values are extracted as follows:

• For the interval $10-14$, the lower class limit is $10$.
• For the interval $15-19$, the lower class limit is $15$.
• For the interval $20-24$, the lower class limit is $20$.
• For the interval $25-29$, the lower class limit is $25$.
• For the interval $30-34$, the lower class limit is $30$.
• For the interval $35-39$, the lower class limit is $35$.
• For the interval $40-44$, the lower class limit is $40$.
