Given

μ=1000, σ=240

 

Consider

P(X<900)=P(X-μσ<900-1000240)

=P(Z<-0.42)

=P(Z>0.42)

=0.33724 From std normal table

I have some problems, help:
Let ( X , A 1 , ν ) be a probability space. Let A : L 1 L 1 be a contraction such that A : L L is also a contraction. Suppose A preserves positivity.
In a proof of why A : L p L p is a contraction for every 1 p < , my lecture notes state that for all f 0, we have
A f p = sup g 0 , g q = 1 X ( A f g ) ,
where 1 p + 1 q = 1.
Why does the above equality hold? The strangest part to me is the fact that the LHS has a power of 1 p outside of the integral X | A f | p , but in the RHS the integral is not being raised to any power. I've tried to raise both sides to p but I could not do much with this. If it helps, this came up in the study of conditional expectations.
