Answer:
Mean = 11.8
Step-by-step explanation:
Given the following data;
Total number of cars (n) = 5
Number of cars (x) = 1, 2, 3, 4, 5
Frequency (F) = 5, 10, 7, 2, 1
F(x) = (1*5) + (2*10) + (3*7) + (4*2) + (5*1)
F(x) = 5 + 20 + 21 + 8 + 5
F(x) = 59
To find the mean;
Mean = F(x)/n
Mean = 59/5
Mean = 11.8
