12.
Female: 7.65
Male: 9.25
13.
Female: 8.26
Male: 9.2
Step-by-step explanation:
For 12, write out all of the numbers in numerical order. Then find whichever number in the middle. In this case, it is two numbers (7.5 and 7.8) and (9.2 and 9.3). Add them up and divide. That will get you your median. 7.65 and 9.25.
For 13, add up all of the numbers and divide by how many there are (in this case 10). That will give you your mean. 8.26 and 9.2.
Hope this helps. Sorry if I'm wrong.
