Median = 15

Range = 9

25th percentile = 14

75th percentile = 17

Interquartile range = 3

Step-by-step explanation:

=>The median in a box-and-whisker plot is indicated by the vertical line that divides the box into two.

The median in the box plot above is 15

=>The range is the difference between the highest value and the lowest value. The lowest value is indicated at our left, where the whisker starts from (11), while the highest value in the data set is indicated at our far right where the other whisker ends (20).

Range = 20 - 11 = 9

=>25th percentile is same as lower quartile, which is indicated on the box plot at the begining of the rectangular box from our left = 14

=>75th percentile is same as upper quartile, which is located at the end of the rectangular box to our right = 17

=>Interquartile range = 75th percentile - 25th percentile = 17 - 14 = 3

answer: 1, 3 and 5 are correct
