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 α = 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. Use the P-value Method

Mouse	1	2	3	4	5	6
weight before	23.6	22.3	19.3	22.4	21.5	19.1
weight after	23.5	22.2	19.1	22.4	21.5	19.0
