The gender differences in attitudes toward violent movies is to be investigated. Suppose the sample consisted of 45 men with an average age of 25, and 55 women, with an average age of 35. Further, suppose that 36 of the sampled men showed a video hire history indicating that over half the videos they hired were “violent”. By contrast, only 17 of the sampled women had a history indicating over half their hired videos were “violent”. The data are then tabulated as: refer to attached photo. The store manager thinks this two-by-two table (for which she has calculated an odds ratio of 8.941) shows clearly that men tend to hire violent movies more often than women. Do you agree with her?
