    Hello,

    would appreciate any help for this. Just confused as to what to say.

    So we are given that Zi ~ N(0,1) and we need to state what type of distribution and parameters random variable V will have.

    V = (Sum from i=1 to n) * (aiZi + bi), where ai and bi are real constants.


    I've tried finding the mean by taking expectations but I get confused with the aiZi part.

    I know they're looking for something like V ~ N(Mean, Variance)

    Any help??
