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 = 0.01, 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 2 3 4 5 6 Weight (before) 21.6 19.2 20.7 21.2 22.2 20.5 Weight (after) 21.5 19.3 20.6 21.3 22.0 20.5 1 A. Pneumonia causes weight loss in mice. B. Weight loss causes pneumonia in mice C.
