Answer:
85
Step-by-step explanation:
Wages per day No.of workers fₓ
(x) (f)
50 2 100
60 4 240
70 8 560
80 12 960
90 10 900
100 6 600
110 8 880
--- -------
50 4240
∴ Mean = ∑fₓ/∑f
= 4240/50
= 84.8
= ~85.
Second part:
Given that the number of workers is doubled.
Mean remains the same = 85.
Hope it helps!
∴ Mean = ∑fₓ/∑f
= 4240/50
= 84.8
= ~85.
