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?
This is what I got, but not sure if it is right...
3.8-2(1.5)= .8 and 3.8+2(1.5)= 6.8 so will the observation fall between .8 and 6.8???
Thankds
