Answer 5

please allow him to post his question :/

Answer 14

sorry statistics isnt my area

Answer 15

@maddie0603 do you have any idea

Answer 16

nope

Answer 17

if X is a random variable, then E[X] is a number independent of x, let me call it c, then E[E[X]]=E[c]=c, so E[E[X]]^2=c^2=(E[X])^2.

Answer 18

Fyi, when you encounter E[X|Y] where X and Y are rvs, which is called conditional expectation, then E[X\Y] is a rv itself. :)

Answer 19

i agree with both, people can some times it depends on what they choose on, so it makes it true and false lolz
