QuestionFind the lower class limits, upper class limits, class width, midpoints, boundaries, and total individuals for:
Age (yr) Frequency 20-29: 27, 30-39: 33, 40-49: 15, 50-59: 4, 60-69: 5, 70-79: 2, 80-89: 2.

Studdy Solution
The total number of individuals is the sum of the frequencies of all classes. To calculate this, we add up all the frequencies$$Total\, individuals =27 +33 +15 +4 +5 +2 +2 =88$$
