Step-by-step explanation:
Solution :-
Arithmetic Mean = Sum of all observations/Number of observations
Observations = 10.25, 9, 4.75, 8, 2.65, 12, 2.35
Total number of observations = 7
Arithmetic Mean = (10.25 + 9 + 4.75 + 8 + 2.65 + 12 + 2.35)/7
⇒ 49/7
⇒ 7
Hence, arithmetic mean of the given data is 7.
