    Hi all,
    I was wondering if someone could please help me with this. I wasn't able to fully grasp it from the examiner's report solution.

    Here's the question.
    Many thanks,
    Tom

    One variable of interest, T, in the description of a physical process can be modelled as T=XY where X and Y are random variables such that
    X ~ N(200, 100) and Y depends on X in such a way that Y|X=x ~(x,1)

    Simulate two observations of T, using the following pairs of random numbers (observations of a uniform (0,1) random variable), explaining your method and calculate clearly:

    Random numbers
    0.5714, 0.8238
    0.3192, 0.6844

    If you could show your working then I can help with what it is that's causing you grief.
