Answer

     526.857


Explanation

Mean = (Σfx)/(Σf)

Σfx = 248 + 2(567) = 3(1402) + 4(728) + 5(419) + 6(456) + 7(208)

      =  14,752

Σf =  1+2+3+4+5+6+7

    = 28

Mean = (Σfx)/(Σf)

          =  14,752/28

          = 526.857

The estimated mean is the average of the data give. It is in form of a grouped data so I used to formula;

mean = (Σfx)/(Σf)

Answer:

Step-by-step explanation:
