Simulation for the Chapter Problem: The Chapter Problem describes a situation in which 1009 consumers were surveyed and asked if they were comfortable having drones deliver their purchases, and 545 of them responded with "no." Section 8-2 discusses the formal hypothesis test of the claim that a majority of consumers are not comfortable with drones delivering their purchases. This project involves a different approach, which consists of simulations. The basic ida is to assume that there is a 0.5 probability of selecting a consumer and getting one not comfortable with drones. Then we will simulate 1009 consumers using the 0.5 probability, and we will repeat this simulation 100 times to see how often the results are as extreme as or more extreme than the 545 "no" responses that are obtained. The simulation is essentailly the same as repeating this process 100 times: toss 1009 coins and see if heads turn up 545 or more times. Making sense of it all: Among the 100 simulated surveys of 1009 consumers, how many of them resulted in 545 or more consumers who said "no"? What does that result suggest about 0.5 being the correct probability? What does that suggest about the claim that "a majority of consumers are not comfortable with drones delivering their purchases"? Does the actual survey result of 545 consumers saying "no" support the claim that a majority of consumers are not comfortable with drones delivering their purchases?
