In the paper titled "Hunters ring dinner bell for ravens..." (White, 2005), ecologist Crow White asked the question whether ravens actually fly towards (not away from!?) the sound of gunshots, to scavenge the carcass they might *find. He went to twelve locations, counted the number of ravens he could see, then shot his gun, waited ten minutes, and counted again. Results are below. Before: 2,1,4,1,2,5,2,0,1,2,5,2 After: 4,0,7,3,3,6,2,1,4,4,7,3 Let my be the true mean number of ravens before the gunshot, and pen is the true mean number of ravens after the gunshot. We want to test Ho : #1 #2 against Ha : #1 The test statistic is Enter your answer correct to 2 decimal places. This statistic would come from a t distribution with 22 degrees of freedom distribution if Ho were true. The P-value is Enter your answer correct to 3 decimal places. So we conclude that O There is no evidence for Ho, that is, there is no evidence that there is no difference in ravens before and after gunshots. O There is no evidence against Ho, that is, there is no evidence that there are more ravens after gunshots. O There is strong evidence for Ho, that is, there is strong evidence that there is no difference in ravens before and after gunshots. O There is strong evidence against Ho, that is, there is strong evidence that there are more ravens after gunshots
