Suppose that the average waiting time for a patient at a physician$$s office is just over $29$ minutes. To address the issue of long patients$,$ wait times, some physicians$$ offices are using wait$-$tracking systems to notify patients of expected wait times. Patients can adjust their arrival times based on this information and spend less time in waiting rooms. The following data show wait times $($in minutes$)$ for a sample of patients at offices that do not have a wait$-$tracking system and wait times for a sample of patients at offices with such systems. The data are stored in HI$6007$ Group Assignment T$12024$ data file $($sheet $1).$ Without Wait$-$Tracking System With Wait$-$Tracking System $243167111714201831124437129231316123715$ a$)$ Calculate the mean and m
