A researcher proposed that perceptions of threat produce higher endorsements for military action. He split his participants into two groups. One group saw photos of the Twin Towers immediately after 9-11; the other group read a newspaper article reporting the attacks. After this exposure, he asked all participants about their endorsement for various levels of military actions against ISIL (from 1 being none to 10 being all-out war). He reported the below data. Using these data, test his hypothesis with the appropriate statistic. Show all work, hypothesis testing logic, and formulae. Make sure to test for effect size. Finally, clearly report your findings in a Results paragraph (you may exclude the confidence interval for now).
