Answer 1

Answer:

24.21

Explanation:

Modal Class = 20 - 30

Lower Limit, l = 20

Height, h = 30 - 20 = 10

Frequency of Modal Class, f1 = 46

Frequency of Class Succeeding Modal Class, f2 = 35

Frequency of Class preceding Modal Class, f0 = 38

Mode = l + (f1 - f0)/(2 × f1 - f0 - f2) × h

= 20 + (46 - 38)÷(2 × 46 - 38 - 35) × 10 = 24.21
