Asked by sam
A rocket fuel is to contain percent X of a particular chemical. The specification limits for X are 30 to 35%. The manufacturer will make a profit Q(x) on fuel per gallon as follows.
Q(x)=
10 cents if 30<=x<=35
5 cents if 35<x<40 or 25<x<30
-10 cents otherwise
Assuming X has a normal distribution with mean 33 and standard deviation 3, calculate expected profit, E(Q(X)).
I don't understand how to determine E(Q(X)) without a pdf.
