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 alphaαequals=0.050, 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

MOUSE	1	2	3	4	5	6
WEIGHT (BEFORE)	22.8	22.7	22.3	21.3	21.9	20.4
WEIGHT(AFTER)	21.3	21.9	21.5	21.0	21.0	19.2

Answer 1

as test statistic falls in rejection region ; we reject null hypothesis and conclude that there is enough evidence to support the​ scientist's claim that pneumonia causes weight loss in mice
