Answer:
the range of ages of 5 teachers is 26
Step-by-step explanation:
the ages of 5 teachers in a school are 32,41,28,54 and 35 then the range of ages of 5 teachers is
Sum of Ages of Teacher = 32 + 41 + 28 + 54 + 35 = 190
Tachers = 5
Mean Age = 190/5 = 38
To find Range of Age
We need to put ages in ascending order
28 , 32 , 35 , 41 , 54
Range = Max age - Min Age = 54 - 28 = 26
the range of ages of 5 teachers is 26
