Ahealth psychologist conducted an experiment in which participants watched a film that either did or did not include
a person being injured because of not wearing a seat belt. a week later, as part of a seemingly different study, these
same participants reported how important they thought it was to wear seat belts. the 22 participants who had seen the
injury film gave a mean rating of 8.3, with an estimated population standard deviation of 1.6. the 30 participants in the
control condition had a mean of 7.4 with an estimated population standard deviation of 2.2. using the .01 significance
level, does seeing a movie where a person gets injured due to not wearing a seat belt make attitudes more positive
towards seat belt usage as indicated by higher ratings?
