Question: A survey found that the American family generates an average of 19.4 pounds of glass garbage per year. Assume the standard deviation is 2.98 pounds. Find the probability that the mean of the sample of 64 families will between 18 and 20 pounds. (Why can you assume this sample is normally distributed??)
