(b) what are Ho and Ha? (c) with alpha=.05, what is rcrit ?Solve the following problems based on the step-by-step procedure of the Non-Parametric Tests. Show complete solutions and answer. The table below lists body temperature of seven subjects at 8AM on Days 1 and 2. The data are matched pairs because each pair of temperatures (in degree Fahrenheit) is measured from the sample person. Use Wilcoxon signed-rank test and a 0.10 significance level to test the claim of no difference between body temperatures at 8AM on both days. Temperature at 8AM on Day 1 98.2 96.6 97.4 97.4 98.2 97.4 97.8 Temperature at 8AM on Day 2 97.0 96.8 96.6 96.6 96.2 97.6 98.6
