Extracted text: A local church had a "drive by food drive" on Easter Sunday, where anyone could drive by and drop off non-perishable food items for local food pantries. Usually the quantity averages 5.1 pounds per donation with a standard deviation of sigma = 1 pounds. This year, they checked 57 of the donations and found the average was x-bar = 8 pounds of food donated per person. They want to see if this is significantly different from the usual amount. What is the standard error of the mean? Round your answer to three decimal places.
