Answer:
D. The new box plot will be positively skewed.
Explanation:
We have been given a box plot which represents the the heights (in feet) of a sample of pine trees.
We are asked to determine that affect of adding a pine tree that is 140 feet tall to the sample.
We can see from our box plot that the tallest pine tree is 75 feet and 140 is approximately 2 times greater than 75.
After adding the a tree that is 140 feet tall, the maximum height will be 140 and our right whisker will be at point 140.
Since we know that for a positive skewed data, the tail of the distribution is longer on the right hand side.
As 140 is a extreme positive outlier for our given data set, therefore, after adding a tree that is 140 feet tall our box plot will be positively skewed and option D is the correct choice.
