Mean of 15 observations is 200. If one observation is
excluded, their mean is 198. Find the excluded
observation
Answers
Answer:
228
Step-by-step explanation:
Given---
Mean of 15 observations = 200
Total Sum of all Observations = 15 × 200
= 3000
On Excluding an Observations,
The Mean of Remaining 14 Observations is 198.
Thus, Total Sum of all 14 Observations = 198 × 14
= 2772
Excluded Observations = Total of 15 observations - Rest of 14 Observations.
= 3000 - 2772
= 228.
Thus, the Value of the Excluded Observations is 228.
