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 claim? Assume the samples are random and dependent, and the population is normally distributed, Complete parts (a) through (e) below. Mouse 1 2 3 5 6 0 Weight (before) 20 9 20 4 22.9 22.9 22 3 22.2 Weight (after) 20 8 20 4 22 8 23.0 22 1 22 2 (b) Find the critical value(s) and identify the rejection region(s) Select the correct choice below and fill in any answer boxes to complete your choice (Round to three decimal places as needed ) O A t> O B. (c) Calculate d and Sd a =(Round to three decimal places as needed.) rces Calculate Sd Sd =(Round to three decimal places as needed.) (d) Find the standardized test statistic t. 1=(Round to three decimal places as needed) ary (e) Decide whether to reject or fail to reject the null hypothesis and interpret the decision in the context of the original claim. ons the null hypothesis. There enough evidence to the claim that causes in mice Time Remaining: 01:27:50 Next
