As part of your work for an environmental group, you want to see if the mean amount of waste generated per adult in your community is less than the national average of 5 pounds per day. You take a simple random sample of 23 adults in your community and find that they average 4 pounds with a standard deviation of 1.5 pounds. Suppose you know the amount of waste generated per day follows a normal distribution.
