If need help after the second attempt to this question, click Show Detailed Solution button below for formula and a similar problem. A researcher believes a new diet will have a positive impact on the health of adult lab mice but the effects on the weight of the mice are unknown. ctor A sample of 10 mice was obtained and the mice were weighed before and after the diet treatment.

After downloading the file, you may want to save it as an Excel Workbook. Use 1% level of significance to decide whether there is sufficient evidence that the mean weight before the diet is greater than the mean weight after the diet. You may also assume that the samples are from normal populations. Procedure: Select an answer Assumptions: (select everything that applies) The number of positive and negative responses are both greater than 10 for both samples Paired samples Population standard deviations are known Independent samples Population standard deviation are unknown but assumed equal Simple random samples Sample sizes are both greater than 30 Normal populations Population standard deviation are unknown UP T On here to search
