According to the American psychological Association, members with a doctorate or a full-time teaching appointment earn, on the average, $82,500 per year with a standard deviation of $6000. An investigator wishes to determine whether $82,500 is also the main salary for all female members with a doctorate and a full-time teaching appointment.
