The arithmetic mean of the observations 61, 33, 94, 48, 36, 93, 73, 94 and 53 is:
Given:
Observations: 61, 33, 94, 48, 36, 93, 73, 94, 53
Total number of observations (n) = 9
Formula Used:
Arithmetic Mean =
Solution:
Find the sum of all the observations:
Sum = 61 + 33 + 94 + 48 + 36 + 93 + 73 + 94 + 53
Sum = 585
Mean =
Mean = 65
Final Answer
So the correct answer is (c)
