People suffering from Obsessive Compulsive Disorder (OCD) spend an average of 3.2 hours per day with a standard deviation of .6 hours engaging in compulsive behaviors. A psychoanalyst theorizes that flooding people with the subject of their obsessive thoughts (e.g. making someone with obsessive thoughts of disease and contagion sit in a dumpster for an hour) will teach them that they have nothing to fear, so it will decrease the amount of time spent engaging in compulsive behaviors. The clinical psychologist tests this theory by selecting a random sample of 36 people suffering from OCD and makes them spend an hour doing a highly challenging activity that is the subject of their obsessive thoughts. After the flooding exercise, the participants spent an average of 3.7 hours per day engaging in compulsive behaviors. Conduct a two-tailed hypothesis test with a significance level of α = .10 to determine if flooding decreased the amount of time spent engaging in compulsive behaviors. H0=? H1=? a=?
