In order to determine what the fees at the new structure should be, the daily fees collected during a three month period (66 weekdays) at another parking facility averaged $126 with a standard deviation of $15.

The consultant, who advised the city on this project, predicted that the parking revenues would average $130 per day. Based on your confidence interval, do you think the consultant was correct? Explain.
