Question
A scientist claims that pneumonia causes weight loss in mice. The table shows the weights (in grams) of six mice before infection and two days after infection. At a=0.10, is there enough evidence to support the scientist's claim? Assume the
samples are random and dependent, and the population is normally distributed. Complete parts (a) through (e) below.
