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 2 3 5 6 Weight (before) 19.2 23.8 19.1 21.5 23.5 22.7 Weight (after) 17.9 22.9 18.4 21.1 22.4 21.4What is the claim? A. Weight gain causes pneumonia in mice. B. Weight loss causes pneumonia in mice. C. Pneumonia causes weight loss in mice. O D. Pneumonia causes weight gain in mice. Let ud be the hypothesized mean of the difference in the weights (before - after). What are Ho and Ha? OA. Ho: Ha # 0 O B. Ho: Ha Sd O C. Ho: Ha SO Ha : Had =0 Ha: Hd > d Ha:p. >0 OD. Ho: Hd = 0 OE.

(d) Find the standardized test statistic t. (Round to three decimal places as needed.)(e) Decide whether to reject or fail to reject the null hypothesis and interpret the decision in the context of the original claim. the null hypothesis. There enough evidence to the claim that causes n mice
