Question: An Evil Genius is trying to develop an army of flying monkeys. Don’t ask why. She would like the Monkeys to be around 250 lbs. with a wingspan of 8’.

Her first attempt with variety A produced 40 monkeys with an average weight of 245 lbs. with a standard deviation of 40 lbs. Based on this sample does this data give good evidence that the true mean weight of Monkeys is less than 250 lbs.?
