Answer:

B) Interquartile range

Step-by-step explanation:

Since there are some students that do not eat fast food at all, their amounts spent monthly would be $0.  These are much different than the rest of the data, and thus are outliers.

Outliers can greatly affect the mean.  This tells us the mean may not be the best measure.

Since the mean is affected by outliers, the standard deviation is not the best measure either.

Adding data points of 0 will also affect the range.  This leaves the interquartile range as the better measure.

Answer:

The students can group themselves in 360360 ways

Step-by-step explanation:

For this exercise we need to use the following equation:

\frac{n!}{n1!*n2!*...*nk!}

This equation give us the number of assignation of n elements in k cell, where n1, n2, ..nk are the element that are in every cell

In this case we have 15 student that need to be assign in three vehicles with an specific capacity. This vehicles would be the equivalent to cells, so we can write the equation as:

  \frac{15!}{7!*5!*3!}

Because the first vehicle have 7 seating, the second vehicle have 5 seating and the third vehicle have 3 seating.

Solving the equation we get 360360 ways to organized 15 students in three vehicles with capacity of 7, 5  and 3 seating.
