A friend asked me to post this here for them, if anyone can help solve it that would be much appreciated.



DEADLINE: Due tomorrow, so if a reply could be given by this evening that would be great.

Quote from: blalp on Feb 11, 2016, 02:29 PMwhich class is this for?  Stats?
Unsure, but it's for a class of ages 16-17 if that means anything. I'm sure the answer isn't super high tier though?

I may have found the issue if anyone wants to take a look at it if I'm wrong here but:

He cannot use the relative frequency and times that with the midpoint. He would need a total amount of boys (a number, say 20 boys) and times that with the relative frequency before he times it with the midpoint.

So if total amount of boys is 20 it would (in the first case) be:

(20*0.3) * 1 = 6

I haven't learned about stats yet, so I'm just guessing here xd
