1, You decide to conduct a study on whether cell phone use by a driver increases the aggression of OTHER drivers. You make a simulated driving experiment in which participants are behind another driver when a stop light changes from red to green, but the lead driver does not move. You record how long it takes before each participant honks the car horn at the lead driver. Half of the participants follow a lead driver who is obviously talking on a cell phone, while the other half follow a driver who is not using a cell phone.
