Answer:
7.25 ounces
Step-by-step explanation:
The sum of weights is the mean weight times the number of apples.
sum of 9 = 7.5×9 = 67.5 . . . ounces
sum of 3 = 8×3 = 24 . . . ounces
Then the sum of the weights of the remaining 6 is ...
67.5 -24 = 43.5 . . . ounces
The mean weight of those 6 is ...
(total weight of 6)/6 = mean weight of 6
(43.5 oz)/(6) = 7.25 oz
The mean weight of the other 6 is 7.25 oz.
_____
<em>Additional comment</em>
If some have an average weight that is greater than the mean of all, the remaining must have an average weight that is less than the mean of all.
