Question

l. Let yt = et + Xet-i be a sequence of independent identically distributed (i.i.d.) random variables, where X is a random variable with mean and variance o,{et} is a sequence of i.i.d. random variables with zero-mean and variance o?. Furthermore, X and {et} are independent. Is {yt} a weakly stationary process? If this is true, calculate the autocovariance function of{yt}.
