- 6.523
- 6.345
- 6.235
- 6.325
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The arithmetic mean is the sum of the numbers divided by the total number of items: \[ \text{Mean} = \frac{7.6 + 6.8 + 5.4 + 6.4 + 7.2 + (4)8 + 6.6 + 5.8}{8} = \frac{5(2)6}{8} = 6.325. \]
