Please use the following information for the next 6 questions. A study tested whether people's belief in the supernatural can change. Five people completed a measure of belief in the supernatural (high scores indicate high levels of belief) before and after watching a documentary attempting to disprove the existence of the supernatural. Participants' scores are listed below. Assume that the researcher predicted participants to believe less in the supernatural after watching the documentary (but still a two-tailed test). Participant Before After Difference Deviation (diff-M) Squared Deviation 4 3 1-4= -3 9 7 6 6-4= 2 DWAN 8 7 1-4= -3 4 9 2 7 7-4= 3 10 5 5 5-4= 1 Mean (before) = 7.6 Sum = 20 sum = 0 Sum (SS) = 32 Mean (after) = 3.6 Mean (diff) =4 Question 1) What is the sample variance (S?)
