The following box-and-whisker plots represent the average high temperatures (in °F) for two cities in the United States. Determine the approximate median, range, and interquartile range for the plot representing San Diego.
Determine the approximate median, range, and interquartile range for the plot representing Boston.
Using complete sentences, make two inferences comparing the data sets.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

the correct answers i think are b. and d.

give me brainliest if it is correct!
