its a "One Sample T Test (z test)" hope you can help me out with steps too, since im really confused. thank you! The average American throws away 4.6 pounds of rubbish every day, according to Reader's Digest. A Vermont town started a Going Green program and pushed residents to recycle more and reduce daily trash. To estimate the average amount of trash in their municipality, 18 random houses were asked to weigh their trash on the same day. The sample averaged 3.89 pounds with a standard deviation of 1.322. Is there proof that Vermont's towns today generate less waste than American households? Use a 0.05 significance threshold and normal weights
