We could assume the relationship is roughly proportional, meaning 6th and 7th graders could work in the realm of 6.RP and 7.RP with this problem. The data is extremely linear, almost a perfect correlation, so you could use this activity as a way to introduce linear relationships or focus more on building a line of best fit.
