I had a Stats test today. Heres a question i was wondering about..see if im right..I cant remember the exact words, but you will get the basic idea.
Theres a class.
Then the said the percentages for left handed girls, left handed boys, right handed girls, right handed boys. They had a table like this..
Boy X X #
Girl X X #
# # #
Where I have a #...they had a percentage
Where I have an X...there was nothing there.
So they say that the left handed girl is independent of left hands...i think thats what they said.
Question: How many left handed girls are there?
Multiple choice...they were like 2 5 7 10 and cant define
Would it be cant define? Cus they are independent?
