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 of= 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 2 3 4 5 6 2 Weight (before) 20.3 20.2 23.2 23.6 19.6 23.8 Weight (after) 20.2 20.3 23.1 23.7 19.6 23.7 (a) Identify the claim and state Ho and Ha What is the claim? O A. Weight loss causes pneumonia in mice. O B. Pneumonia causes weight gain in mice. O C. Weight gain causes pneumonia in mice. O D. Pneumonia causes weight loss in mice
