Please answer b,c and d

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 3 4 5 6 2 Welght (before) 19.1 22 2 20 3 19.2 21.1 19.8 Wolght (after) 19.0 22 2 20.1 19.1 20.9 19.8 Ha Hy > d Maily FU Ha Py O B. to O C. > (c) Calculate d and sd d= (Round to three decimal places as needed.) Calculate Sd. Sa = (Round to three decimal places as needed.) (d) Find the standardized test statistic t. 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. Roject the null hypothesis. There is enough evidence to support the claim that pruemonia causes weight loss in mice
