The dot plot represents the distribution of wages earned during a one-week period by 12 college students. What is the median? Interpret this value based on the situation.

• $119; Most students made $119 per week.

• $118; Half of the students earned $118 or less and half of the students earned $118 or more.

• $118; The average weekly wage was $118.

• $119; Some of the students earned less than $119 and some of the students earned more than $119
