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. Mouse 1 2 22.7 21.6 20.6 20.6 21.7 22.9 21.3 20.9 19.9 20.2 20.6 21.7 3 4 5 Weight (before) Weight (after) C. Pneumonia causes weight loss in mice. O D. Weight gain causes pneumonia in mice.
