Triphammer Road is a busy street that passes through a residential neighborhood. Residents there are concerned that vehicles traveling on Triphammer often exceed the posted speed limit of 30 miles per hour. The local police sometimes place a radar speed detector by the side of the road; as a vehicle approaches, this detector displays the vehicle's speed to its driver. The police hope that drivers will slow down if they are reminded of their speed. The local residents are not convinced that such a passive method is helping the problem. They wish to persuade the village to add extra police patrols. To help their case, a resident stood where he could see the detector and recorded the speed of vehicles passing it during a 15 minute period one day. The speeds of the vehicles are given. Let's build a 90% confidence interval for the mean speed of all vehicles traveling on Triphammer Road. 29 29 24 34 34 34 34 32 36 28 31 31 30 27 34 29 37 36 38 29 31 26 NAME
