## anonymous 5 years ago The typical American generates about 3.8 pounds of solid trash per day with a standard deviation of 1.5 pounds. Assuming that the histogram for trash produced per day is approx. bell shaped, between what two values will 95% of the observation fall? Thanks

From the empirical rule, about 95% of the data will lie between: $\mu -2\sigma$and$\mu+2\sigma$So your lower bound will be approximately,$3.8 - 2 \times 1.5 = 0.8$and$3.8+2 \times 1.5=6.8$Hence, 95% of the observations would fall between 0.8 lb and 6.8 lb.
