An annual forecast of the Florida grapefruit crop is based on an actual count of grapefruits on a random sample of trees.

Suppose 5 grapefruit trees are randomly selected and the fruit of each tree is counted.

tree	# fruit
1	80
2	60
3	100
4	40
5	120

1. Build a 95% confidence interval estimate of the population mean number of grapefruits per tree.

2. If there are 75,000 grapefruit trees in Florida, give a 95% confidence interval estimate of the total number of grapefruits harvested.
