Answer: Mode
<u>Step-by-step explanation:</u>
The given data set is: 10, 10, 12, 13, 15
Mean is the average - find the sum of the data set and divide by the number of terms in the set: 
Mean = 12
Median is the middle term (when the data set is ordered from least to greatest).
Median = 12
Mode is the term that appears the most.
Mode = 10
Since you want to show that the prices are low, you would choose the lowest value. 10 is lower than 12, so the Mode is lower than either the Mean or the Median.
Choice D : look at where you think the line would be if it followed the direction of the data so that about half of the points fell above the line and half below. The two most important things to note are the slope of the line and y intercept.
This is a negative relationship as the line falls as you read it from left to right. That eliminates choice C. Next, it appears the line of best fit would have a y intercept around 10 on the y axis and then fall down and to the right cutting the data. Note that choices A and B have y intercepts that don't make sense for the data. Choice D does have a y intercept of 10 and a negative slope.
The answer is C. Circle
