ippose Ai k, and all random variables are independent, i.e. A; s are dependent and identically distributed, Z₂'s independent and identically distributed and X; and Z; are independent. State the distribution o ach of the following random variables if it is named distribution or otherwise state 'unknown'. Justify your answers; no derivations are ecessary!!
