During Reconstruction, many small white farmers, thrown into poverty by the war, entered into cotton production, a major change from prewar days when they concentrated on growing food for their own families. Out of the conflicts on the plantations, new systems of labor slowly emerged to take the place of slavery.
The density of an egg will vary slightly between each egg. To determine it exactly you will need to find its mass and its volume. Density is mass divided by volume. The average density of an egg is 1.031 g/cm 3 (grams per centimeter cubed) or 1.031g/ml (grams per milliliter). The density of water is 1 g/ml. Salt adds mass while adding very little volume so it is a good additive to make the density higher.
Hens usually begin laying eggs when they are about 6 months old. Young hens tend to lay smaller eggs, often weighing less that the desired minimum weight of 54 grams. a. The average weight of the eggs produced by the young hens is 50.9 grams, and only 28% of their eggs exceed the desired minimum weight.If a Normal model is appropriate, what would you predict the standard deviation of the egg weights be? â5.3 grams b. By the time the hens have reached a year, the eggs they produce average 67.1 grams with a standard deviation of 6.4 grams.
