1. How large of a sample do you need to estimate the average pounds of garbage within 2 pounds with 95% confidence?
2. How large of a sample do you need to estimate the proportion of homes that recycle within 10% and with 99% confidence? (Use .65 as the estimate of the true proportion since 39 of the 60 in the sample are recyclers)
