It is 6 but I did not graph it cuz that would take to long. I used an app called wabbitemu that has the ti calculators on it.

6.5 becuase you find the middle using numbers 3,6,7,9. Then you find the middle of 6 and 7. Then you have your answer, you would do the same for the upper quartile, cross of 9, 10, 12, 13. The middle would be 11 becuase it is the middle of 10 and 12.
