Streeling University surveyed a random sample of employees to estimate the frequency of sexually inappropriate comments they had heard at work during the last month. 32 of 80 respondents said they had heard such comments. The survey was repeated after all employees had attended a required training seminar on appropriate workplace behavior. After the seminar, 36 of 120 respondents said they had heard such comments. At α = .10, was the proportion reporting inappropriate comments lower after the seminar?
