# In a study to test the effects of science fiction movies

. In a study to test the effects of science fiction movies on people’s belief in the supernatural, sevenpeople completed a measure of belief in the supernatural before and after watching a popular sciencefiction movie. Participants’ scores are listed below with high scores indicating higher levels of belief….ing the .01 significance level, test the experimenter’s assumption that the participants’ belief in thesupernatural would change after watching the movie.

A swimming school claimed that after taking lessons from their instructors the average seven-year-oldwould be able to swim across an Olympic-sized pool in significantly less time than the average. Theaverage time is 3 minutes. To test this claim, a psychologist arranged for eight randomly selected sevenyear-old children to take lessons at the school and recorded how long it took each child to swim across apool at the end of the lessons. The times (in seconds) were 92, 111, 120, 75, 132, 84, 73, and 114. Usethe .05 significance level to determine if the students did swim significantly faster than the average.A) What is the appropriate test for this data?B) Conduct the appropriate hypothesis test.

A health psychologist conducted an experiment in which some participants watched a film that includeda person being injured because of not wearing a seat belt while other participants watched a film thatdid not include this. They then reported how important they thought it was to wear seat belts on a scalefrom 0 to10 (0 = not important at all, 10 = extremely important). Use the .01 significance level todetermine if seeing a movie where a person gets injured due to not wearing a seat belt make attitudesmore positive towards seat belt usage.

The company wants to know if their customers will drink more coffee if the coffeehouse is decorated in a Paris theme or in a San Francisco theme. The psychologist sets up two similarrooms with the two themes. Eight students spend an afternoon in each room, drinking all the coffee theylike. The order in which they sit in the rooms is rotated so that half spend their first afternoon in the Parisroom and half in the San Francisco room. The amount of coffee each participant drinks in each room isshown below. Use the .05 significance level to determine if there a significant difference between thenumbers of cups of coffee consumed in the two rooms.
