just to reiterate, you should really look at the within fruit data before just taking the mean. Is it consistent? Are there any unusual points? If it is consistent and there are not any unusual points, then the mean will be an appropriate statistic. You might also want the standard deviation as that represents within fruit variation. You might find factors that effect variability (vs. just the mean).
