Given:
The numbers = 3, 3, 4, 5 and 5
To Find:
The arithmetic mean of the numbers
Solution:
Numbers = 3, 3, 4, 5 and 5
Thus, total numbers are five.
Using the formula of arithmetic mean -
= ( Sum of Observation) / (Total numbers of Observations)
Substituting the values
= 3 + 3 + 4 + 5 + 5 / 5
= 20/5
= 4
Answer: The arithmetic mean of the numbers is 4.
