    I have a question in my assignmet which I don't know where to start and how it works so i was hoping some of you might have ideas or know how to attack this question:

    A random variable, W, has mean 16, variance 4 and ‘standardised’ skewness = 0.5.
    Using varying numbers of terms from a Taylor series approximation, calculate three
    different approximations for E (W1/3). Also approximate Var (W1/3) using a Taylor
    series approximation.

    E(W/3) = E(W)/3 = 16/3
    Var(W/3) = Var(W)/3^2 = 4/9
