What I would do is find the mean of each data set first. Do you know how to calculate mean @deer_slayer13?

deer_slayer13 · Answer

not really im lazy

anonymous · Answer

Ok, so what you would do is add up all the values in the first data set. So can you tell me what that would be?

deer_slayer13 · Answer

40

We're just working for the 1st row. The sum of 6+5+2+8+6 is 27.

27

Ok, I just worked the WHOLE problem out. I ended up 3.32, which is not a choice. I'm not sure if I did something wrong or they did something wrong. I'll be back in a second after I work this out okay?

deer_slayer13 · Answer

ok

anonymous · Answer

I still keep coming up with 3.32. Let me refer you to someone who might be able to figure out the errors. Are you a 100% positive that those are the choices?
