Answer:
answer is in the attached picture
Step-by-step explanation:
To construct the box-and-whisker plot from the given data we first need to find the 3rd quartile.
To find the 3rd quartile we will use the interquartile range and 1st quartile.
Interquartile range = 3rd quartile - 1st quartile
(substitute the values given in the question)
3 = 3rd quartile - 6
3rd quartile = 3 + 6
3rd quartile = 9
hence we now have the complete data to construct the box-and-whiskers plot.
The plot is in the attached picture.
