Answer:
Range = 9
Explanation:
From the question,
Mean = summation data/Total frequency
Mean = (6+7+x+13+10)/5
If the mean is 8,
8 = (36+x)/5
Solve for x
36+x = 8×5
36+x = 40
x = 40-36
x = 4.
Range is the difference between the biggest and the smallest value in a given distribution.
from the above,
Range = 13-4
Range = 9
