Answer:
The standard deviation of the sample mean is 16.98.
Explanation:
The standard deviation of the sample mean differences is given as by the difference of the 2 standard deviations.This is given as
Difference of standard deviations=21.2-17.6 = 3.6
Now the ratio of the difference to the largest standard difference is given as
Ratio=3.6/21.2=0.1698
Converting this into percentage as 0.1698x100=16.98
The standard deviation of the sample mean is 16.98.

Answer:
The agriculture in the western hemisphere developed nearly simultaneously as in Asia/eastern hemisphere.
Explanation:
A is not correct because it was almost at the same time where agriculture started developing in both hemispheres, with the evidence suggesting a difference of only a few hundred years.
B is not correct because the western hemisphere would not have been able to produce any great civilizations if agriculture was not well developed and the basis of the economy.
C is correct because independently, at nearly the same time, the people living in both hemispheres started to plant and rise some of the wild plants that they thought have great potential, thus giving birth to agriculture.
D is not correct because the climate conditions in the western hemisphere at that time would not have allowed people to engage in agriculture, especially not in large scale agriculture and to be able to produce enough food for themselves and have a surplus.
The Freedman's Bureau was created to help former black slaves and poor whites in the South after the Civil War. Giving them education and medical help was very important in helping them recover from the revolution and helped the freedmen to be able to live on their own.
