Task 2: Both Ozzy Osbourne and Judas priest have been accused of putting backward masked messages on their albums that sublimially influence poor unsuspecting teenagers into doing things like blowing their heads off with shotguns. A psychologist was interested in whether backward masked messages could have an effect. He created a version of Britney Spears's Baby one more time' that contained the masked message 'deliver your sould to the dark lord' repeated in the chorus. He took this version, and the original, and played one version (randomly) to a group of 32 people, Six months later he played them whatever version they hadn't heard the time before. So each person heard both the original and the version with the masked message, but at different points in time. The psychologist measured the number of goats that were sacrificed in the week after listening to each vversion. Test the hypothesis that the backward message would lead to more goats being sacrificed using Wilcoxon signed-rank test (DarkLord.sav)
