A consumer agency purchased 20 pairs of RoadRunner in-line skates from sports retailers chosen at random across the U.S. It found that 10% of the pairs (i.e., two) had defective wheels. However, the skate manufacturer claims that its tests show that no more than 2% of all RoadRunner pairs it distributes have defective wheels.
How unusual would a result like the consumer agencys be if, as the skate manufacturer claims, only 2% of all RoadRunner pairs have defective wheels?
Describe, in principle, how you would use ProbSim to investigate the question. (You dont need to provide details of setting up ProbSim. Youll provide that information in the next question. Instead, focus on the overall logic of your strategy.
