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 = 0101, 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 9 Weight (before) 23.7 20.4 21 2 19.3 19.4 23.2 Weight (after) 23 5 20.3 21.1 19.2 19.2 23.1 What is the claim? O A. Weight loss causes pneumonia in mice. O B. Pneumonia causes weight loss in mice. O C. Weight gain causes pneumonia in mice. O D. Pneumonia causes weight gain in mice. Let uq be the hypothesized mean of the difference in the weights (before - after). What are Ho and Ha? OA. Ho Hd = 0 OB. Ho Ha 20 O C. Ho Ha # 0 Ha Ha * 0 Ha Hd d Ha Ha > 0 Ha Ha OB. 1= ort> O C. <
