Question

The mean of the following data is x 26 14 13
f 10 7 3

Answer 1

Answer:

Mean = 132.33

Step-by-step explanation:

x1 = 26, f1 = 10

x2 = 14, f2 = 7

x3 = 13, f3 = 3

Mean = (Sum of the product of frequencies and variables)/Number of variables

Mean = [(10)(26) + (7)(14) + (3)(13) ] / 3

Mean = [ 260 + 98 + 39 ] / 3

Mean = 397 / 3

Mean = 132.33
