(a) Generate a systematic random sample of 5 rabbits (circle them above). Then find the mean cuteness amongst these rabbits.

(b) Some rabbits are "bigger" than others ('baby' rabbits vs 'big' rabbits). Randomly select three baby rabbits and three big

rabbits and compute the weighted mean cuteness of both stratas (combined). [You must decide what weights to assign].
