Given data

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.
