Answer 2

Answer:

Mode = 3.286

Step-by-step explanation:

To find Mode Class

Arrange data

Here, maximum frequency is 8.

∴ The mode class is 3-5.

∴L=lower boundary point of mode class =3

∴f1= frequency of the mode class =8

∴f0= frequency of the preceding class =7

 ∴f2= frequency of the succedding class =2

∴c= class length of mode ceass =2

$= l + ( \frac{f1 - f0}{2 \times f1 - f0 - f2} ) \times c$

Z= 3 +( (8 - 7 )÷ ( 2×8-7-2))×2

= 3 +(1÷ ( 16-9))×2

= 3 + (1÷ 7 )× 2

= 3 + .143 × 2

= 3 + 0.286

= 3.286

All the best ❤
