-12.2, 13.2-13.3) Question 4 of 20 This test: 100 point(s) possible This question: 5 point(s) possible Submit test Listed below are actual high temperatures and the high temperatures forecast one day in advance. Use a 0.05 significance level to test the claim that the population of differences has a median of zero. What do the results suggest about the accuracy of the predictions? Actual high temperature 82 3 76 85 84 82 78 High temperature forecast one day before 88 81 78 76 88 81 85 80 Data table Click the icon to view the critical values for the Wilcoxon signed-ranks test. 0.005 (one tail) | 0.01 (one tail) 0.025 (one tail) |0.05 (one tail) 0.01 (two tails) 0.02 (two tails) 0.05 (two tails) |0.10 (two tails) What are the hypotheses for this test?
