Amounts spent by a sample of 200 customers at a retail store are summarized in the following relative frequency distribution.  The median amount will fall in the following class interval:
A)0 up to 10 
B)10 up to 20 
C)20 up to 30 
D)30 up to 40

Quizplus · Accepted Answer

The median is the middle value when the data is arranged in ascending or descending order. From the relative frequency distribution, we can see that the cumulative frequency up to the class interval 20 up to 30 is 0.50, which means that half of the customers spent less than or equal to $25 (the upper limit of the class interval). Therefore, the median amount spent will fall in the class interval 20 up to 30.
