A p-chart would be the most appropriate as it is used to monitor the proportion of defectives in a process. In this case, the proportion of students who wait longer than 5 minutes in line would be considered the defective. P-charts are useful for monitoring processes that have a variable sample size, which may be the case with the number of students in line each day.
