To solve this problem, we need to find the medians and the interquartile range of the data set. Then we can approximate the difference of the medians as a multiple of the interquartile range.
Without knowing the data set, we cannot find the exact medians and interquartile range. Therefore, we cannot find the exact answer to this problem. It is possible that the answer is one of the options given, but we cannot determine that without more information.

Atenea makes 7 snack bags with 13 pounds of trail mix each, for a total of:
7 x 13 = 91 pounds of trail mix used for the week.
This means Atenea has:
256 - 91 = 165 pounds of trail mix left that she gives to her brother.
Therefore, the answer is:
165 pounds, which is Option D.
Brad and Tom are comparing their classes' scores on a math test. Both of their classes had mean scores of 80 on the test, but Brad's class had a range of 6 while Tom's class had a range of 30. If the highest possible score was 100, which class had the LOWEST score in it?

D Brad's class had the lowest score in it.
Bot answer me
The answer to the question is:
It cannot be determined from the information given.
The range of a set of numbers tells us the difference between the highest and the lowest numbers in the set. It does not give us any information about where the lowest score occurred. Therefore, we cannot determine from the range of the scores which class had the lowest score.

D kinds of sports played by student athletes
The answer is:
Weight of a basket of apples.
Quantitative variables are those that are numerical and can be measured with a unit of measurement, such as weight, height, temperature, or time. Varieties of apples sold in the grocery store, favorite tourist attractions, and kinds of sports played by student athletes are not quantitative variables because they are not numerical and cannot be measured with a unit of measurement.
