Question

The mean of the following data is

x 26 14 13

f 10 7 3​

Answer 1

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 frequency and variables)/ number valuables

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

mean = [260 + 98 + 39] / 3

mean = 397 / 3

mean = 132.33
