Provide brief explanation for choice of answer

A study was conducted to determine the growth performance
of swine among varying levels of protein supplements (20% and 40%) and
percent of cassava root (20%, 30%, 40%) as additive in rice bran. All the levels of
factors were purposively selected. The treatment combinations were randomly
assigned to swine of the same initial weight. Percent gain in weight were
obtained after 2 months. Suppose all the assumptions for the parametric test
were satisfied. The following results were obtained using R commander:
