An article in Agricultural Engineering (December 1964, pp. 672–673) described an experiment in which the daily weight gain of swine is evaluated at different levels of housing temperature. The mean weight of each group of swine at the start of the experiment is considered to be a nuisance factor. The data from this experiment are as follows:

hello, can someone help me answer this question please?

An article in Agricultural Engineering (December 1964, pp. 672-673) described an experiment in which
the daily weight gain of swine is evaluated at different levels of housing temperature. The mean weight
of each group of swine at the start of the experiment is considered to be a nuisance factor. The data
from this experiment are as follows:
