A researcher designs an experiment using two drugs, she prepares 15 independent flasks of yeast growth medium and yeast cells. She adds tunicamycin (T) or caffeine (C) to 5 flasks each. Remaining 5 flasks get no drugs (ND). Doubling time of the yeast cells are measured in each flask, data is provided below:

Test if mean doubling time is different than others in at least one growth condition (ND, T or C), using
a non-parametric method and report an approximate p-value for the level of significance. What is the hypotheses and the assumptions of this test?
