3.5. To form a slightly different random sum, let &, ,, . . . be independent identically distributed random variables and let N be a nonnegative integer-valued random variable, independent of , .... The first two moments are

E[] =, E[N] = v, Var[] =, Var[N] = 7,

Determine the mean and variance of the random sum

E[] =, E[N] = v, Var[] =, Var[N] = 7,
