Researchers at the University of Rochester studied the friction that occurs in the paper-feeding process of a photocopier (Journal of Engineering for Industry, May 1993). The experiment involved monitoring the displacement of individual sheets of paper in a stack fed through the copier. If no sheet except the top one moved more than 25% of the total stroke distance, the feed was considered successful. In a stack of 100 sheets of paper, the feeding process was successful 94 times. The success rate of the feeder is designed to be .90. Test to determine whether the true success rate of the feeder exceeds .90. Use α = .10.
