Each of five different stores sells a quart of milk for the following prices:
$1.50, $1.55, $1.80, $1.70, $1.50
Find the median.

The correct answer is: 1.55

Step 1 of 1:
Given the dataset, $1.50, $1.55, $1.80, $1.70, $1.50
Arrange the data set in order (ascending), $1.50, $1.50, $1.55, $1.70, $1.80
There are 5 (odd no. of) data points in the dataset.
So, the median is (5+1)/2 = 3rd data point
Mid value is the median, $1.50, $1.50, $1.55, $1.70, $1.80
1.55 is the median of the data set.
Final Answer:
The right choice is-- d. 1.55
