It's one question
A scientist claims that prieumonia causes weight loss in mice. The table shows the weights (in grams) of six mice before infection and two days after infection. Al = 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.
