The weights (in kg) of 15 workers in factory
Weight (in kg) 60 63 66 72 75
Number of workers 4 5 3 1 2
Lets we have to prepare the table for calculating the mean
Weight(in kg) (x) Number of workers (f) fx
60 4 240
63 5 315
66 3 198
72 1 72
75 2 150
∑f=15 ∑fx=975
we know that
Mean =∑f∑fx =15975
Mean =65
Mean weight=65kg
Step-by-step explanation:
Hope it helps.
