The first two shipping companies provided their data from a sample of drivers in a table.

Company C showed its data in a dot plot.


Answer the questions to compare the mean number of deliveries for the three companies.

1. How many drivers did company C use in its sample?

2. What is the MAD for company C's data? Show your work.

3. Which company had the greatest mean number of deliveries?

4. Compare the means for companies A and B. By how many times the MAD do their means differ? Show your work.

Answer 1

Answer:

The means differ by 4 times the MAD.

Step-by-step explanation:

I may be missing something, but this is how I interpret it.

The mean number of deliveries for company A is 6, and the mean for company B is 14. Lastly, the mean absolute deviation (MAD) for both companies is 2.

$14-6=8\\8\div2=4$

The means differ by 8, and that is 4 times the MAD, so the means differ by 4 times the MAD.
