However, I will give you a start. Convert all to cubic yards. Even so, there are several problems in making a comparison. Here are some examples: Knowing the size of the yard = (80/3)^2 sq yards is not really helpful, because you don't know the depth of the soil that will ...

If the median is from a larger population, then it can be true. If the median is just for the 10 students, then it cannot be true. The median is the 50th percentile.

The mean serves as a fulcrum for the distribution, so it is affected by extreme scores in either direction. If they had a day in which they sold very many cameras, this would bias the mean. I would choose the median (50th percentile).
