Statistics: Z-test – #29447


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’.

A sample of size 40 of Type B monkeys had a sample mean of 230 lbs. It is known that the standard deviation of this type of monkey is 32 lbs. Does this give good that Type B monkeys have weights less than 250 lbs?
