You are doing some statistical process control and consulting for Zoo Pets, Inc. You are helping them measure their giraffe food. Ideally, they want to measure the giraffe food into prepackaged bags of exactly 89 pounds apiece.

The bags don't all weigh 89 pounds; they are normally distributed with a mean of 89 pounds and a stdev of 5.7 pounds.

If you choose a bag at random, how many pounds of giraffe food would you expect it to contain?
