Suppose you work at a company that is trying to make a sponge design that can absorb the most amount of water. Based on the company's theoretical models, this sponge's design was expected to hold 0.93 ml/cm3. However, after testing many sponges of this design, you show that the average amount of water it can hold is 0.66 0.13 ml/cm3. Based on your findings, what are some possible conclusions might you draw?
