Answer 1

To solve this question, first we have to calculate the median of the of the data to begin, because that is the middle line that is shown in the box and whisker plot, remember that the median is the middle value of a data set (after you arrange the data from lowest to highest), in this case the median is 422600.

The ends of the box are upper and lower quartiles, to get them, after you ordered the data from lowerst to highest you divide the data in 4, the value for the upper quartile is 432650 and for the lower quartile is 406500.

Now we check the ghaps given and get that the B option is the one that conveys the information, you can notice this by observing that the median is closest to the lower quartile than the it is to the upper one so the line in the graph is goint to be more to the left.
