Enter letter corresponding to most correct answer CW Question 13 (1 point) One of the most difficult things to do in statistics is to determine the correct hypothesis test to do for a given scenario. Determine the most appropriate hypothesis test to use for the following scenario: ************************** In a study to test the effects of science fiction movies on people's belief in the supernatural, seven people completed a measure of belief in the supernatural before and after watching a popular science fiction movie. Participants' scores are listed below with high scores indicating higher levels of belief. PartiCIpant Supernatural Belief Supernatural Belief Score BEFORE Score AFTER Watching Watching Sci-Fi Movie Sci-Fi Movie E 1 7 Using the .01 significance level, does participants' belief in the supernatural change after watching the movie?

Determine the null hypothesis and the alternative hypothesis: \"no:*********************** A Harris Poll conducted October 28, 2008 surveyed 2119 US adults who were asked "when you think of rising health care costs, who do you think is most responsible?" One theory is that 50% of adults blame insurance companies, 10% blame pharmaceutical companies, 10% blame Federal and state governments, 10% blame hospitals, 10% blame physicians, 5% blame some other entity, and 5% are unsure who is most responsible.
