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 0.05, 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 Weight (before) Weight (after) 1 2 3 4 5 D 22.9 23.1 21.1 20.1 19.1 20.1 6 21.5 22.3 20.3 19.6 18.1 19.0 OC. Pneumonia causes weight gain in mice. D. Pneumonia causes weight loss in mice. Let be the hypothesized mean of the difference in the weights (before-after). What are Ho and H₂? OA. Ho Hd 20 H₂: <0 OD.
