Correct Answer - Option 1 : 5
Given:
X = (1, 3, 3, 7, 5, 0, 2, 9, 11, 8, 6)
Formula Used:
Arithmetic mean = Sum of terms/Number of terms
Calculations:
Number of terms = 11
Sum of terms = 1 + 3 + 3 + 7 + 5 + 0 + 2 + 9 + 11 + 8 + 6
⇒ Sum of terms = 55
Arithmetic mean = Sum of terms/Number of terms
⇒ Arithmetic mean = 55/11
⇒ Arithmetic mean = 5
∴ The arithmetic mean of the given data is 5.
