paraphrase think the group data represents the data the best because we are looking if one solution or all can cause a difference to the data and it supports the alternative hypothesis that ATP and Salts would make a difference to the length. The class data has a change in solutions A,B,C when we are looking for no change so it rejected the null hypothesis. Mostly finding that if one of the solutions will have a greater cause in muscle contraction as to why I think the group data represent the Solution when ATP and salts are added the muscle contraction is great unlike ATP alone and Salt by itself
