City planners are trying to decide among various parking plan options. Before making a decision, they wish to test the downtown merchants' claim that shoppers park for an average of 47 minutes in the downtown area. The planners record parking durations of 225 randomly selected shoppers and find that the average parking time was 50 minutes with a standard deviation of 27 minutes. Is there evidence at the 0.05 significance level that the merchants' claim is wrong?
