The average response time to a bank robbery is 9 minutes. A local community wants to improve on this time, so they implement advanced training seminars. The local community predicts that the advanced training seminars will lower the average response time. They find that the new response time for a sample of 36 police officers is 8 minutes with a standard deviation of 4.2. Test whether this advanced training seminar reduced response time at a .05 level of significance.
