Question A1 a) i) Population regression function states merely that the expected value of Webobservable, the same concept of an ‘expectation value’ is applied to non-Hermitean operators which do not represent observable properties of a system. Thus if Aˆ is not Hermitean and hence not an observable we cannot make use of the idea of a collection of results of experiments over which an average is taken to arrive at an expectation value. streaky windows after cleaning

WebExpected value Consider a random variable Y = r(X) for some function r, e.g. Y = X2 + 3 so in this case r(x) = x2 + 3. It turns out (and we have already used) that E(r(X)) = Z 1 1 r(x)f(x)dx: This is not obvious since by de nition E(r(X)) = R 1 1 xf Y (x)dx where f Y (x) is the probability density function of Y = r(X).
