Female gully cats are thought to be more aggressive when they have kittens. In order to test the null hypothesis of no difference, aggressiveness scores on a scale of 1-10 (with 10 being most aggressive) were obtained for a group of 7 females without kittens and for the same 7 female cats when they had kittens. The data is given below: Cat ID Without Kittens With Kittens 065040-1 Note that the data is not normally distributed. Perform a Wilcoxon signed rank test to answer the question. State the null/alternative hypotheses
