Answer:
29) 55
Or
25
Step-by-step explanation:
29). CI f
10-25 2
25-40 3
40-55 7
55-70 6
79-85 6
Modal class( largest number)= 40-55
mode = D1 = D1 × h
D1 + D2
= 40 + 4 × 15
4+1
= 40+ 60
4
= 40+15
= 55
Or
CI. f. Cf
0-10 5 5
10-20 8 13
20-30 20 33
30-40 15 48
40-50 7 55
50-60 5 60
N = 60 ( Cf last number)
Median = N
2
= 60
2
= 30
Median = L+ N _ Cf × h
2
f
= 20+ 30-20 × h
20
= 20+10 × 10
20
= 20+100
20
= 20+5
= 25
