    I would appreciate it if someone could provide the solution to QA1 of the attatched exam paper.

    A1 (a) Give the definitions of the autocovariance and autocorrelation of a time series model.
    (b) Calculate the autocovariance and autocorrelation function for the time series
    Y = 3 + Zt + 1/2Zt-1 + 1/5Zt-2,
    where {Zt} are independent N(O, 1) random variables.
