Lesson 2-7, Example 1 Check Understanding

1. Wages The employee who earns $8.25 per hour resigns. She is replaced by an employee earning $7.50 per hour. Find the mean, median, and mode of the data.
   1. $7.25/h; about $6.38/h; $6.25/h
   2. about $6.53/h; $6.50/h; $6.25/h
   3. about $6.53/h; about $6.38/h; $6.25/h
   4. $7.25/h; $6.50/h; 5

   3. Mean; none of the hourly wages are outliers.
