Acomparative box plot is shown for two data sets. which statement is true? ( me and if you're not 100% sure)

answer choices

a. at least 50% of the data for each set is between 13 and 16.

b. less than 25% of the data for the sets overlap.

c. more than 25% of the data for each set is greater than 15.

d. at least 75% of the data is greater than 16.

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.

A dilation used to create an image larger than the original is called an enlargement. 
A dilation used to create an image smaller than the original is called a reduction.

To describe a dilation we need two things: a scale factor and a center of dilation. The scale
factor tells us how the size of the “new” figure compares to the size of the old one. If the scale
factor is 1, then the two figures will be exactly the same size. If it is less than 1, the new figure
will be similar to the old one, but smaller, and if it is greater than 1, the new figure will still be
similar to the old one, but will be larger.

HOW TO FIND THE SCALE FACTOR

If you are given two shapes and need to find the scale factor, you must know which one was the original and which one is the image or the new shape.  Then you need to know the length of corresponding sides and set them up in a ratio like so:
